AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HASTINGS NE
342 AM CST TUE FEB 9 2016

.SHORT TERM...(TODAY AND TONIGHT)
ISSUED AT 328 AM CST TUE FEB 9 2016

SATELLITE AND SURFACE OBSERVATIONS SHOW SOME MID LEVEL CLOUDS MOVING
INTO THE FORECAST AREA. MOST OF THEM ARE IN THE WESTERN PART OF THE
AREA AT THIS TIME.

NORTHWEST FLOW WILL CONTINUE ACROSS THE AREA THROUGH THE PERIOD.
LOOKING UPSTREAM...THERE ARE MORE CLOUDS AND WITH THE NORTHWEST FLOW
THERE WILL CONTINUE TO BE AN INCREASE IN CLOUD COVER DURING THE DAY
TODAY. THE CLOUDS WILL GRADUALLY LOWER DURING THE DAY AS WELL. THERE
WILL BE COLD ADVECTION ACROSS THE AREA. TEMPERATURES TODAY WILL BE
ON THE COLD SIDE WITH READINGS IN THE UPPER 20S TO UPPER 30S FOR
MOST LOCATIONS. THE SNOW FREE AREAS FAR SOUTH IN THE FORECAST AREA
WILL REACH AROUND 40 DEGREES.

THERE WILL BE A WEAK UPPER LEVEL WAVE THAT MOVES THROUGH THE AREA
TONIGHT. MOST OF THE ENERGY WITH THE WAVE WILL BE TO THE NORTH OF
THE FORECAST AREA BUT THERE COULD BE A FEW FLURRIES IN THE NORTHERN
PART OF THE AREA. THESE SHOULD BE MAINLY NORTH OF INTERSTATE 80.

.LONG TERM...(WEDNESDAY THROUGH MONDAY)
ISSUED AT 342 AM CST TUE FEB 9 2016

THE MAIN FORECAST ISSUE WILL DETERMINING TEMPERATURES.

WE WILL REMAIN IN NORTHWEST FLOW AS THE UPPER LEVEL RIDGE IN THE
WEST AND TROUGH IN THE EAST DEAMPLIFY. A JET STREAK COULD LINGER
SOME FLURRIES IN OUR NORTHEAST WEDNESDAY MORNING...BUT THIS WILL BE
ON ITS WAY OUT WEDNESDAY MORNING. I ANTICIPATE SOME DOWNSLOPE FLOW
AT THE SURFACE WITH A WEST/NORTHWEST COMPONENT. 850 MB TEMPERATURES
WILL WARM SIGNIFICANTLY ON WEDNESDAY AFTERNOON...ALTHOUGH THE
GRADIENT WILL BE STRONG FROM NORTHEAST TO SOUTHWEST...RANGING FROM
NEAR 5C IN OUR NORTHEAST CORNER TO AS HIGH AS 12C IN OUR SOUTHWEST.
DESPITE THE REMAINING SNOW...I CAN SEE THE TRI-CITIES EASILY MAKING
THE 40S THIS DAY...THANKS TO THE WEST COMPONENT OF THE WIND.

I EXPECT A BIT OF A COOL DOWN FOR THURSDAY/FRIDAY AS DE-
AMPLIFICATION OF THE PATTER ALOFT ALLOWS COOLER AIR IN...ESPECIALLY
NORTHEAST...THEN A 1044 MB ARCTIC HIGH RELEASES SOME COLDER
TEMPERATURES ON SATURDAY. I ACTUALLY LOWERED TEMPERATURES FROM
INITIALIZED GRIDS TO MID 20S IN THE TRI-CITIES. HOWEVER...WE ARE
ESSENTIALLY SIDE-SWIPED BY THE PUSH OF THE COLD AIR TO THE
EAST...AND WE WILL FIND OURSELVES ON THE BACKSIDE OF THE SURFACE
HIGH BY FRIDAY WITH A WARM-UP ANTICIPATED INTO NEXT WEEK. IN
FACT...WE COULD HAVE SEVERAL DAYS OF ABOVE NORMAL TEMPERATURES NEXT
WEEK. I KEPT SUNDAY DRY...BUT A QUICK-MOVING SHORTWAVE TROUGH IS
ADVERTISED BY MODELS THAT COULD GIVE US A LITTLE PRECIPITATION.
MOISTURE IS LIMITED...SO I KEPT THIS DRY FOR NOW.
