610 AM CST THU MAR 10 2016 The 08z surface analysis showed a cold front extending from Effingham to Paris. With cloud cover persistent for much of the day, and slightly colder air behind the cold front, highs today will be about 10 degrees cooler than yesterday. Winds will be southerly for a few hours this morning southeast of I-70, but the majority of the area will see northerly winds prevail between 10 to 15 mph as the cold front departs. The only real dry period will be tonight into Friday evening, as high pressure drifts eastward across the Great Lakes. Weekend rainfall chances will be traced to the disposition of the upper low currently spinning over central Mexico.
DEEP UPPER LOW OVER NORTHERN MEXICO IS RESPONSIBLE FOR THE IMPRESSIVE PLUME OF MOISTURE THAT IS SPREADING NORTHWARD ACROSS THE LOWER AND MID MS VALLEYS THIS MORNING. THIS FEATURE WILL WORK TO THE NORTH AS A WARM FRONT FRI NT.
HIGH PRESSURE WILL BUILD ON FRIDAY BEFORE A SERIES OF DISTURBANCES BRINGS INCREASING CHANCES FOR RAIN TO START THE COMING WEEK. SPURRED ALONG BY AN UPPER-LEVEL TROUGH APPROACHING THE GREAT LAKES. UPPER-LEVEL TROUGH NEARS LAKE MICHIGAN TONIGHT AND REALLY BEGINS TO FLATTEN THE EASTERN CONUS RIDGE THAT HAD BEEN IN PLACE. MUCH DRIER AND COOLER AIR WILL MOVE IN. ALTHOUGH TEMPERATURES ARE EXPECTED TO BE COOLER THAN THE LAST SEVERAL DAYS.
HIGHLY AMPLIFIED PATTERN CONTINUES ACROSS THE SOUTHERN HALF OF NORTH AMERICA AS A VERY STRONG/DEEP MID/UPPER LOW SPINS OVER NORTHERN MEXICO AND A STRONG HIGH PRESSURE EXTENDS FROM THE NW CARIBBEAN THROUGH FLORIDA AND ALL THE WAY UP THE EASTERN SEABOARD OF THE UNITED STATES. WHILE THE MEXICO LOW PUMPS COPIOUS MOISTURE AND FLOODING RAIN TO THE LOWER MISSISSIPPI VALLEY AND PARTS OF TEXAS, FLORIDA REMAINS UNDER THE PROTECTIVE INFLUENCE OF THE HIGH PRESSURE AREA.
Damp, drizzly conditions have developed over the area during the past several hours with temperatures in the low/mid 50s. Split flow aloft has resulted in a cut off low centered over Mexico, with a weak, positively trough slowly edging east across the northern tier of states. Eventually, by later this afternoon, the trough over the northern tier of states will press far enough east to shunt drier air into the area and shift light rain to the southeast. The latest round of model output continues to lift the upper low over Mexico northward with time. Have maintained a slight chance mention of thunder as the upper low moves over the area this weekend.

1108 PM CST WED NOV 11 2015 Powerful, deep low pressure system currently centered in the vicinity of the IA/NE/MO borders has dropped down to around 989/990mb as of the last hour. Behind a fropa roaring through, this dynamic system is ushering in much drier air (dewpoints have been crashing across eastern KS and into far western MO) and eventually the chillier air from the north as the cold front makes its way through. Across northern MO tonight, where dewpoint depressions are much closer together and better atmospheric moisture is available, could see a few showers streaking through on the backside of the low but these should be relatively light in nature and not widespread. Once the high traverses into the eastern U.
WE WILL SEE WARMER TEMPERATURES THE NEXT SEVERAL DAYS.
THIS IS ASSOCIATED WITH AN APPROACHING COLD FRONT THAT WILL BRING MUCH COOLER AND DRIER AIR TO THE REGION. TEMPERATURES ARE RUNNING IN THE UPPER 60S WHICH IS SOME 15 DEGREES WARMER THAN THIS TIME 24 HOURS AGO. TEMPERATURES TODAY AND TONIGHT WILL BE COOLER THAN WE HAVE BEEN SEEING BUT NOT AS COOL AS WE WILL SEE LATER IN THE WEEK AS SOMEWHAT ZONAL FLOW WILL BE IN PLACE IN THE MID-LEVELS. LOWS FRIDAY NIGHT MAY DROP CLOSE TO FREEZING IN THE GOLDEN TRIANGLE REGION WHICH WOULD MARK THE FIRST FREEZE OF THE FALL.
DRY CONDITIONS AND HIGH TEMPERATURES SEVERAL DEGREES WARMER THAN TODAY CAN BE EXPECTED OVER THE REGION.

LIGHT RAIN AND SNOW SHOWERS WERE MOVING EAST ACROSS THE REGION THIS EVENING AS A WEAK SHORT WAVE TROUGH PASSES THROUGH. THIS TROUGH WILL PASS LATE TONIGHT AND EARLY THURSDAY MORNING.
20Z water vapor shows a closed upper low lifting across southeast NEB. For tonight, the forecast is for the strong cyclone to continue moving northeast with dry air and large scale subsidence continuing to overspread the forecast area. Have expanded the high wind warning to include the entire forecast area until 6 pm. Think the low clouds that are wrapping around the back side of the low will be temporary as dry air advection ultimately win out with skies clearing out overnight.
WIND IN CENTRAL AND NORTH CENTRAL NEBRASKA WAS LOWER THAN THE HIGH WIND CRITERIA. SO WE HAVE CANCELED THE HIGH WIND WARNING. WIND IN CENTRAL AND NORTH CENTRAL NEBRASKA WAS LOWER THAN THE HIGH WIND CRITERIA. SO WE HAVE CANCELED THE HIGH WIND WARNING.
/ISSUED 317 PM CST WED NOV 11 2015/ THE LONG ADVERTISED COLD FRONT IS CURRENTLY MOVING SOUTHWARD ACROSS THE SOUTHERN TEXAS PANHANDLE. THE COOLER AIRMASS BEHIND THE COLD FRONT WILL ALLOW TEMPERATURES TO DROP INTO THE MID 30S TO UPPER 20S OVERNIGHT TONIGHT. A FREEZE WARNING WILL BE ISSUED FOR THE CENTRAL AND NORTHEASTERN TEXAS PANHANDLE AND CENTRAL AND EASTERN OKLAHOMA PANHANDLE COUNTIES AS THESE LOCATIONS ARE EXPECTED TO DROP TO AND BELOW FREEZING. A FROST ADVISORY WILL BE ISSUED FOR THE SOUTHEASTERN TEXAS PANHANDLE AS TEMPERATURES ARE EXPECTED TO REMAIN JUST ABOVE FREEZING. THURSDAY NIGHT INTO FRIDAY MORNING WILL SEE ANOTHER ROUND OF FREEZING TEMPERATURES; POSSIBLY COVERING EVEN MORE LOCATIONS THAN TONIGHT. HAVE HELD OFF ON ISSUING ANY WATCH PRODUCTS TO AVOID CONFUSION GIVEN WE ARE LOOKING AT FREEZING TEMPERATURES TONIGHT.
AS A LINE OF SHOWERS/THUNDERSTORMS AND A COLD FRONT NEARS FROM THE WEST. GIVEN THE HIGHER DEWPOINTS AND A MORE UNSTABLE ATMOSPHERE IN AND AROUND THAT CONVECTION. SOME WINDS WITH/BEHIND THE FRONT MAY GUST TO AROUND 30 MAINLY IN THE HIGHER TERRAIN THU AM.

THE WORST OF THE LOW VISIBILITY SHOULD END BY LATE THIS EVENING.
EXPECT FREEZING TEMPERATURES EAST AND SOUTH OF TUCSON LATE TONIGHT AND EARLY THURSDAY MORNING.
COLD FRONT CURRENTLY MOVING INTO WEST TN PER OBS. THE MORE IMPORTANT ASPECT OF THIS SYSTEM WILL BE THE GUSTY WINDS ASSOCIATED WITH THE COLD FRONTAL PASSAGE. THE HIGHEST ELEVATIONS WILL SEE GUSTS BETWEEN 35 AND 45 MPH. TEMPS WILL BE COOLER TONIGHT BEHIND THE FRONT AS CLEAR SKIES ARE EXPECTED AND COLDER AIR FILTERS IN.
TEMPERATURES WILL THEN CONTINUE ON A MODEST WARMING TREND THROUGH THE END OF THE WEEK AS HIGH PRESSURE BUILDS OVER THE REGION.
435 AM EST THU NOV 12 2015 AN AREA OF SHOWERS AHEAD OF A COLD FRONT HAS MOVED EAST OF THE AREA THIS MORNING. THE COLD FRONT WILL CROSS EARLY THIS MORNING AND USHER IN STRONG WINDS. HIGH PRESSURE WILL BUILD OVER THE MIDWEST ON FRIDAY AS AN UPPER LEVEL TROUGH PASSES BY LATE FRIDAY. TRUE COLD FRONT IS CURRENTLY BISECTING INDIANA AND WILL TRAVERSE EAST THROUGH CWA IN THE 12-15Z TIME FRAME. WINDS WILL SHIFT WEST AND THEN THE HIGHER GUSTS WILL BEGIN TO AFFECT THE AREA. A SECONDARY UPPER LEVEL TROUGH WILL CROSS IN THE LATE DAY AND OVERNIGHT TEMPS WILL DROP TO THE FREEZING MARK FOR JUST ABOUT EVERYONE UNDER RAPIDLY CLEARING SKIES.
AS THE STORM SYSTEM AND COLD FRONT MOVE THROUGH THE REGION. THEN A COOLER TEMPERATURE FORECAST INITIALLY. ASSOCIATED WITH LOW PRESSURE TROUGH. WHICH IS WELL AHEAD OF THE COLD FRONT IN CENTRAL KS. STILL EXPECT THE SURFACE SYSTEM TO LIFT NE AND GRADUALLY MOVE THE WARM FRONT AND LOW PRESSURE TROUGH THROUGH THE STATE. THEN THE COLD FRONT MORE INTO THE EVENING PERIOD.
/ISSUED 353 PM CST WED NOV 11 2015/ (Tonight and Thursday) A Pacific cold front has moved through all but extreme southeast counties as of mid afternoon. A rather extensive but thin cirrus shield will advect northeast across the southeastern half of the forecast area overnight and should keep temperatures from falling below the lower 40s.
1009 PM EST WED FEB 3 2016 WHILE THE MAIN COLD FRONT HAS MOVED EAST OF THE MOUNTAINS.
Overnight lows will bottom out in the low to mid 20s, with the coldest readings in the usual cold air drainage locations. Lots of sunshine will allow for slightly warmer temperatures than what we are seeing today.
DRIER AND COOLER AIR CONTINUES TO MOVE INTO SOUTH CENTRAL TEXAS AS TEMPERATURES REMAIN IN THE 50S TO LOWER 60S. AN UPPER LEVEL TROUGH OVER THE CENTRAL US WILL CONTINUE TO PROGRESS EASTWARD OVER THE NEXT 12-18 HOURS AS THE BASE OF THIS TROUGH MOVES THROUGH THE REGION AROUND SUNRISE THURSDAY MORNING. HIGH PRESSURE AT THE SURFACE AND RELATIVELY CALM WINDS WILL ALLOW FOR STRONG RADIATIONAL COOLING TO GIVE US THE COOLEST NIGHT OF THE FORECAST PERIOD WITH MOST SPOTS BELOW FREEZING. WITH LOWS RANGING FROM THE MID 20S IN THE HILL COUNTRY TO JUST ABOVE FREEZING IN PARTS OF THE COASTAL PLAINS. FIRE WEATHER CONCERNS SHOULD REMAIN JUST BELOW ELEVATED AS WINDS REMAIN BELOW 10 MPH DESPITE MIN RH VALUES IN THE LOWER 20S.
SHOWER ACTIVITY WILL DIMINISH WITH HEIGHTS RISING BY THE EVENING AS WEAK RIDGING BUILDING IN OVER THE AREA.
Dry conditions will persist across western Kansas through Thursday night as short range models indicate a weak upper level ridge moving out of the Central Rockies into the Western High Plains. Warmer temperatures are expected for highs today as the aforementioned westerly downslope flow persists across the region.
