Filling Up
By Todd Nelson
As
I get older, I am finding that there's not enough time. From
accomplishing day to day tasks to finding open spots on an already full
calendar, I sometimes wonder how it all gets done. While the key to
success often means being a good time manager, I often find that
tackling tasks with optimism and drive makes that mountain a little less
hard to climb.
While our calendars are filling up, our rain
gauges are doing the same. Radar estimates show that nearly 1 to 4
inches of rain has fallen across the state since the first of the month.
However, the U.S. Drought Monitor showed minimal improvement in the
state's drought since last week. We've gone from 94 to 92 percent
moderate drought and from 40 to 35 percent severe drought. With
additional heavy rainfall still possible into the upcoming weekend, I
expect additional improvement in those numbers by next week.
After a
soggy start today, weather conditions will be warmer and drier by the
afternoon. Our next storm system blows into town this weekend with
strong to severe thunderstorm chances late Saturday and again Sunday.
Keep an eye on the forecast for potential watches and warnings near you.

Minneapolis Temperature Trend
After
a cool and soggy Thursday, weather conditions will improve Friday as
warmer, drier weather moves in. We'll continue our warming trend as we
head into the weekened with highs approaching 80F! The storm system
responsible for our warming this weekend will also bring a chance of
strong to severe storms with it. Post storm system, it appears we cool
down again into next week. I am hoping we warm up and dry out by
Memorial Weekend; I've got some grilling to do!
_________________________________
Friday Weather Outlook
Temperatures
will be feel quite a bit warmer on Friday after the cool, soggy
Thursday we had. The best chance of highs reaching 70F or better will be
across the southern half of the state, while highs in the northern part
of the state look to still be stuck in the low/mid 60s.
Friday Weather Outlook
Friday
may start on a soggy/puddly note, but with a little clearing and some
sunshine, we should be able to dry out a little through the day. Enjoy
it because weather conditions look to turn unsettled into the weekend.
Although it looks warmer, strong to severe storms may be rolling into
town!
Simulated Radar
The
simulated radar loop below from AM Thursday through PM Saturday shows
the soggy weather Thursday giving way to drier weather Friday, then some
unsettled weather developing later Saturday. Keep an eye on the
forecast over the weekend and strong to severe storms could pop up close
to home.
Rainfall Potential
The image below from suggests nearly 0.5" to 1.0" of rain possible from AM Thursday to PM Saturday.
_____________________________________________
Rainfall Past 14 Days
Radar
estimated rainfall through the first 14 days of the month suggest that
we've seen nearly 2" to 4" of rain in parts of central Minnesota.

Minnesota Drought Update
The
latest update from the U.S. Drought Monitor show a slight improvement
since last week. The MODERATE drought area dropped from near 94% to 92%
and the severe drought dropped from 40% to 35%
Rain Needed to End Drought
Interestingly,
parts of the state still need nearly 5" to 7"+ to end the drought. The
good news is that additional heavy rainfall amounts may still be on the
way over the weekend.
7 Day Precipitation Outlook
According
to NOAA's HPC. the 7 day precipitation outlook still shows some
impressive tallies across parts of the Central U.S. Through midweek next
week, as much as 2" to 4" amounts can't be ruled out!

National Weather Outlook
Our
next storm system across the Western U.S. will continue moving east
through into the upcoming weekend. After a few quiet days, severe
weather, heavy rain and flooding potential looks to ramp back up over
the next few days.
Increasing Instability: CAPE Friday 1pm
This
is a look at the instability by early afternoon Friday. Note the
oranges and reds across parts of the Plains and middle part of the
country. This is where thunderstorms activity would have the best
potential to become strong to severe if they do develop.
Severe Threat Friday
...SUMMARY...
SEVERE THUNDERSTORMS ARE EXPECTED ACROSS PARTS OF THE NORTH CENTRAL
HIGH PLAINS FRIDAY AFTERNOON AND EVENING. MORE ISOLATED SEVERE STORM
DEVELOPMENT IS POSSIBLE SOUTHWARD INTO THE SOUTHERN HIGH PLAINS BY
FRIDAY EVENING. OTHER SCATTERED STRONG TO SEVERE STORMS ARE POSSIBLE
FRIDAY ACROSS PARTS OF THE MIDDLE MISSISSIPPI VALLEY INTO SOUTHERN
PORTIONS OF THE GREAT LAKES REGION. ...SYNOPSIS... A SPLIT IN THE
MID-LATITUDE WESTERLIES WILL PERSIST ACROSS THE NORTHEASTERN PACIFIC
THROUGH THIS PERIOD...WITH MODELS SUGGESTING AN UPPER HIGH CENTER
BECOMING INCREASINGLY PROMINENT OVER NORTHERN BRITISH COLUMBIA AND THE
YUKON TERRITORY. WITHIN THE SOUTHERN STREAM...TO THE SOUTH OF THE
RIDGE...CYCLONIC MID/UPPER FLOW MAY BROADEN ACROSS PARTS OF THE EASTERN
PACIFIC THROUGH MUCH OF THE U.S. PLAINS BY 12Z SATURDAY. ONE OF THE MORE
SIGNIFICANT EMBEDDED SHORT WAVE IMPULSES APPEARS LIKELY TO GRADUALLY
PIVOT FROM THE EASTERN GREAT BASIN THROUGH THE NORTHERN HIGH PLAINS
FRIDAY THROUGH FRIDAY NIGHT. AT THE SAME TIME...THE PRIMARY/STRONGER
PERTURBATION...COMING INCREASINGLY IN PHASE WITH THE SUBTROPICAL
STREAM...IS EXPECTED TO PROGRESS INLAND ACROSS SOUTHERN
CALIFORNIA/NORTHERN BAJA DURING THE DAY...BEFORE CONTINUING EAST OF THE
LOWER COLORADO VALLEY...TOWARD THE SOUTHERN ROCKIES...FRIDAY NIGHT.
AROUND THE NORTHERN PERIPHERY OF DOWNSTREAM AMPLIFYING LARGE-SCALE
RIDGING...ANOTHER SUBSTANTIVE SHORT WAVE TROUGH PROBABLY WILL TRACK FROM
THE GREAT LAKES REGION THROUGH MUCH OF THE NORTHEAST. IN
LOWER-LEVELS...A SURFACE FRONTAL ZONE APPEARS LIKELY TO TEND TO SHIFT
NORTHWARD ACROSS THE NORTHERN TIER STATES...TO THE EAST OF THE
ROCKIES...MORE RAPIDLY THROUGH THE NORTHERN PLAINS AND UPPER MIDWEST
THAN THE LOWER GREAT LAKES REGION. SURFACE TROUGHING WILL PROBABLY
CONTINUE TO DEEPEN TO THE LEE OF THE ROCKIES...WITH MODELS INDICATING A
CONSOLIDATING/DEEPENING LOW CENTER OVER THE NORTHERN HIGH PLAINS BY THE
END OF THE FORECAST PERIOD. EAST OF THE SURFACE TROUGH...AND ALONG/SOUTH
OF THE FRONT...LOWER LEVELS ARE EXPECTED TO CONTINUE TO MOISTEN ON
SOUTHERLY FLOW. BY LATE FRIDAY AFTERNOON...INSOLATION IS EXPECTED TO BE
SUFFICIENT TO SUPPORT CORRIDORS OF MODEST BOUNDARY LAYER DESTABILIZATION
/CHARACTERIZED BY CAPE OF 1000-2000 J PER KG/ ACROSS PARTS OF THE HIGH
PLAINS...AND ACROSS PORTIONS OF THE MIDDLE MISSISSIPPI VALLEY THROUGH
SOUTHERN PORTIONS OF THE GREAT LAKES REGION. MEANWHILE...STRONGEST
VERTICAL SHEAR SHOULD BECOME FOCUSED ACROSS THE NORTH CENTRAL HIGH
PLAINS. HOWEVER...MODEST WESTERLY DEEP LAYER FLOW/SHEAR MAY DEVELOP WITH
THE UPPER IMPULSE...NEAR THE FRONT...ACROSS THE SOUTHERN GREAT LAKES
REGION...PERHAPS ALSO WITH ANOTHER WEAK IMPULSE CROSSING THE MIDDLE
MISSISSIPPI VALLEY. ...HIGH PLAINS... MOISTENING EASTERLY/SOUTHEASTERLY
LOW-LEVEL UPSLOPE FLOW...TO THE NORTHEAST OF A DAYTIME SURFACE LOW
CENTER OVER NORTHEAST COLORADO...IS EXPECTED TO HELP FOCUS PRIMARY STORM
DEVELOPMENT ACROSS THE NORTH CENTRAL HIGH PLAINS FRIDAY AFTERNOON. THIS
SHOULD BE AIDED BY MID/UPPER FORCING ASSOCIATED WITH THE LEAD IMPULSE
MIGRATING OUT OF THE EASTERN GREAT BASIN...WHICH COULD CONTRIBUTE TO THE
INITIATION OF VIGOROUS STORMS ACROSS PARTS OF NORTHEAST
COLORADO/SOUTHEAST WYOMING AS EARLY AS MIDDAY. ACTIVITY SHOULD THEN
DEVELOP/SPREAD NORTHWARD/NORTH NORTHEASTWARD THROUGH MUCH OF WESTERN AND
CENTRAL NEBRASKA AND SOUTHERN SOUTH DAKOTA THROUGH THE REMAINDER OF THE
AFTERNOON AND EVENING HOURS. IN THE PRESENCE OF STRONG DEEP LAYER
SHEAR...AND SIZABLE CLOCKWISE CURVED LOW-LEVEL HODOGRAPHS...ORGANIZED
CONVECTION...INCLUDING SUPERCELLS...WILL SUPPORT THE RISK FOR SEVERE
HAIL AND A FEW TORNADOES INITIALLY...BEFORE THE RISK OF DAMAGING WIND
GUSTS BECOMES MORE PROMINENT FRIDAY EVENING. ISOLATED SUPERCELLS MAY
ALSO NOT BE OUT OF THE QUESTION ALONG THE DRYLINE SOUTHWARD THROUGH THE
CENTRAL AND SOUTHERN HIGH PLAINS LATE FRIDAY AFTERNOON AND EVENING. BUT
PRIMARY THUNDERSTORM DEVELOPMENT MAY AWAIT FORCING WITH THE STRONGER
UPSTREAM IMPULSE...WHICH MAY NOT OCCUR UNTIL LATE FRIDAY NIGHT.
Increasing Instability: CAPE Saturday 4pm
Instability
across middle part of the country really starts to increase by the
afternoon/evening hours on Saturday. At this point, Saturday could be a
fairly interesting day with several areas possibly seeing strong to
severe thunderstorm development.
Severe Threat Saturday
...SUMMARY...
POTENTIAL FOR NUMEROUS STRONG TO SEVERE STORMS WILL EXIST SATURDAY OVER
A LARGE PART OF THE PLAINS INTO A PORTION OF THE MIDDLE AND UPPER
MISSISSIPPI VALLEY REGIONS. LARGE HAIL...DAMAGING WIND AND A FEW
TORNADOES WILL BE POSSIBLE. ...CNTRL THROUGH SRN PLAINS AREA... EARLY
SATURDAY A WARM FRONT SHOULD EXTEND EWD FROM A SFC LOW OVER THE NRN HIGH
PLAINS THROUGH SD...MN AND SRN WI. A DRYLINE/PACIFIC FRONT WILL EXTEND
SWD FROM THIS LOW THROUGH THE HIGH PLAINS INTO WRN TX. MOIST WARM SECTOR
WILL BE IN PLACE EAST OF DRYLINE/PACIFIC FRONT WITH DEWPOINTS FROM THE
UPPER 60S OVER TX AND OK TO THE LOW 60S FARTHER NORTH INTO SD. POTENTIAL
FOR EARLY CONVECTION AND AREAS OF WIDESPREAD CLOUDS REMAIN A
COMPLICATING FACTOR THIS FORECAST. AN AREA OF MOSTLY ELEVATED
THUNDERSTORMS MAY BE ONGOING SATURDAY OVER A PORTION OF THE CNTRL AND
SRN PLAINS WARM SECTOR...AND THIS ACTIVITY WILL SHIFT EWD DURING THE
MORNING. IN WAKE OF EARLY STORMS...A CORRIDOR OF MODERATE INSTABILITY
SHOULD DEVELOP AHEAD OF THE PACIFIC FRONT...AND ADDITIONAL STORMS WILL
LIKELY INITIATE ALONG AND AHEAD OF THIS BOUNDARY AS A STRONG UPPER JET
SWINGS THROUGH BASE OF TROUGH...AUGMENTING DEEP ASCENT. BOTH LOW-LEVEL
AND DEEP SHEAR PROFILES WILL INCREASE DURING THE DAY WITH THE APPROACH
OF THE UPPER JET...BECOMING FAVORABLE FOR ORGANIZED STORMS INCLUDING
SUPERCELLS BY AFTERNOON...THOUGH SOME STORMS MAY ALSO EVOLVE INTO LINE
SEGMENTS AND CLUSTERS. LARGE HAIL...DAMAGING WIND AND A FEW TORNADOES
WILL BE POSSIBLE WITH THIS ACTIVITY. ...NRN PLAINS THROUGH UPPER MS
VALLEY... ELEVATED STORMS MAY BE ONGOING IN VICINITY OF WARM FRONT AS IT
LIFTS NWD THROUGH THE DAKOTAS AND MN DURING THE DAY. THE ATMOSPHERE IS
EXPECTED TO DESTABILIZE IN WAKE OF THIS ACTIVITY AND ADDITIONAL STORMS
WILL LIKELY DEVELOP NEAR TRIPLE POINT OVER WRN/CNTRL ND AND SWWD ALONG
PACIFIC FRONT/DRYLINE. STRONGEST LOW-LEVEL SHEAR WILL EXIST IN VICINITY
OF WARM FRONT WHERE A CONDITIONAL RISK WILL EXIST FOR A FEW TORNADIC
SUPERCELLS. OTHERWISE...PRIMARY THREAT WILL BE DAMAGING WIND AND HAIL
FROM MID AFTERNOON INTO THE EARLY EVENING.
Increasing Instability: CAPE Sunday 1pm
While
not quite as impressive as Friday and Saturday, the instability by
midday Sunday still looks fairly impressive across the middle part of
the country once again.
Severe Threat Sunday
SUNDAY: SEVERE
THREAT WILL SHIFT INTO THE MIDDLE AND UPPER MS VALLEY AND GREAT LAKES
REGION IN ASSOCIATION WITH A PROGRESSIVE UPPER TROUGH AND ITS ATTENDANT
STRONG DEEP-LAYER WIND PROFILES. THE LIKELIHOOD OF ONGOING STORMS RAISES
UNCERTAINTY REGARDING WHERE THE HIGHER SEVERE POTENTIAL WILL
EVOLVE...SO WILL MAINTAIN GENERIC 15% SEVERE PROBABILITY THIS UPDATE.
FARTHER SOUTH...LESS ORGANIZED MULTICELL STORMS WILL DEVELOP THROUGH ERN
TX WARM SECTOR WHERE THE THERMODYNAMIC ENVIRONMENT MAY SUPPORT AT LEAST
A MODEST RISK FOR SEVERE STORMS.

Sierra Nevada Snow Deficit
"Few
things are more important to California’s water supply than the water
content of the mountain snowpack at the start of the state’s warm
season. Winter-type storms and snowfall tend to taper off in April and
May. Temperatures become warmer and days become longer, causing the
snowpack to melt. As spring turns to summer, this melting snow keeps
the state’s rivers and streams—and people’s farms, fields, and taps—from
running dry."
"The snowpack this spring is incredibly
small. These photo-like NASA satellite images contrast the snow extent
in the Southern Sierra Nevada Range Mountains on May 2, 2015, and May
10, 2003, a year when snow conditions were close to the long-term
average. (The large versions of the images show the entire state.)
Instead of gleaming white snow tracing ridges and valleys, large areas
of bare brown rock appear on the mountain summits in the 2015 image."

"Climate Denialists In Congress Acting As NASA's Kryptonite"
"Quick: List the first four words that pop into your mind when you hear NASA.
If
you are like most folks, you hit some mix of astronauts, moon landings,
space telescopes and Mars probes. Those are pretty positive images
representing accomplishments we can all feel proud about.
Astronauts
are, after all, great American heroes. And space telescopes are
reminders of just how smart — and insanely capable — Americans can be.
Put it all together and you can see why NASA does superhero stuff in the
eyes of most people.
It's also stuff that's universally
recognized to be the kind where you absolutely, positively can't afford
to be wrong. And that is why NASA is a real problem for climate
denialism.
If you are intent on convincing people there
is no climate change, then the last thing you want is NASA — with all
its heroism and accuracy — telling folks climate change is real. So,
faced with this dilemma, climate denialist's have come up with a clever
solution: Get NASA out of climate change science."
