.SHORT TERM...TONIGHT. SHORT TERM CONCERNS WILL BE CLOUDS AND
TEMPERATURES ALONG WITH POTENTIAL FOR PATCHY DRIZZLE. AT 20Z...
SURFACE LOW PRESSURE WAS CENTERED OVER EASTERN IOWA WITH MID
TROPOSPHERIC LOW PRESSURE FROM MINNESOTA INTO SOUTH DAKOTA. LIGHT
RAIN AND DRIZZLE WAS ROTATING AROUND THE MID LEVEL LOW TO OUR
NORTH...WITH ABUNDANT MOISTURE ACROSS THE MISSOURI RIVER VALLEY.
THERE HAVE BEEN SOME BREAKS IN THE CLOUDS AND LIFTING OF THE CLOUD
HEIGHTS. DEEPER LOW LEVEL MOISTURE SHOULD MOVE BACK INTO THE AREA
OVERNIGHT. THE BETTER FRONTOGENESIS AND POTENTIAL VORTICITY
REMAINS TO OUR NORTH. WILL HOLD ONTO THE CLOUDS OVERNIGHT AND THIS
SHOULD ALLOW TEMPERATURES TO STAY IN THE UPPER 30S TO AROUND 40
DEGREES OVERNIGHT. NORTHWEST WINDS WILL GENERALLY BE AROUND 5 TO
15 MPH.
ZAPOTOCNY
.LONG TERM...WEDNESDAY THROUGH TUESDAY. UPPER LOW ROTATING THROUGH
THE UPPER MISSISSIPPI RIVER VALLEY COULD STILL BRING A FEW SPRINKLES
OR VERY LIGHT SHOWERS TO THE AREA WEDNESDAY...AS COLD CORE ALOFT
COULD CREATE ENOUGH INSTABILITY TO GENERATE FEW RAIN DROPS THROUGH
THE DAYLIGHT HOURS. WILL STILL BE FAIRLY COOL AND MOSTLY CLOUDY
WEDNESDAY...WITH WINDY CONDITIONS AND TEMPS IN THE UPPER 50S AND
LOWER 60S WITH WINDS OF 20 TO 30 MPH. KEPT THINGS DRY WEDNESDAY
NIGHT AS WE LOSE THE DAYLIGHT WITH LOWS DOWN IN THE LOWER 40S AND
DIMINISHING WINDS.
WE DO FINALLY BEGIN TO WARM UP A BIT ON THURSDAY AS THE UPPER LOW
PULLS TO THE EAST. AGAIN...GIVEN THE COLD TEMPS ALOFT...WOULD NOT BE
SURPRISED IF A FEW SPRINKLES DEVELOP BY LATE MORNING OR EARLY
AFTERNOON ALONG AND EAST OF THE MISSOURI RIVER...BUT TEMPS SHOULD
WARM A WELL INTO THE 60S.
RIDGING BUILDS ACROSS THE CENTRAL PAINS THURSDAY NIGHT AS A
SOUTHERLY FLOW DEVELOPS AHEAD OF THE NEXT COLD FRONT THAT IS
FORECAST INTO THE AREA FRIDAY NIGHT. THIS WINDY SOUTHERLY FLOW
SHOULD BOOST TEMPS INTO THE LOWER TO MID 70S FRIDAY WITH SOUTHERLY
WINDS 20 TO 30 MPH. THIS WILL ALSO BRING DEWPOINTS IN THE 50S BACK
TO THE AREA...WHICH SHOULD HELP MITIGATE ANY FIRE WEATHER ISSUES.
THE FRONT HAS APPEARED TO SLOW DOWN BY ABOUT 6 HOURS...THUS TRIMMED
MOST OF THE CHANCE OF RAIN DURING THE DAYLIGHT ON FRIDAY...BUT
INCREASED POPS INTO THE 50 TO 60 PERCENT RANGE FOR FRIDAY NIGHT WITH
HIGHEST POPS NORTH OF I80. BULK OF THE INSTABILITY SHOULD BE EAST OF
THE AREA BY DAYBREAK SATURDAY...BUT A FEW LINGERING SPRINKLES OR
SHOWERS COULD DEVELOP SATURDAY BEHIND THE FRONT...AGAIN WITH HIGHER
POPS ACROSS NORTHEAST NEBRASKA. TEMPS SHOULD ALSO DROP BACK INTO
THE UPPER 50S TO MID 60S WITH BREEZY NORTHWEST WINDS ONCE AGAIN.
COOL TEMPS STICK AROUND FOR SUNDAY WITH BREEZY CONDITIONS
PREVAILING AS AN UPPER TROUGH SLOWLY MOVES THROUGH THE REGION. THINK
THAT SUNDAY SHOULD BE DRY THOUGH AS MOISTURE APPEARS FAIRLY MEAGER.
CONDITIONS DO IMPROVE BY MONDAY/TUESDAY OF NEXT WEEK AS SURFACE
TEMPS ARE EXPECTED TO MOVE BACK INTO THE MID 60S...WITH DRY WEATHER
CONTINUING.
