231 PM EST FRI FEB 19 2016 CURRENT SATELLITE LOOP SHOWS MOSTLY CLEAR SKIES ACROSS THE AREA AS HIGH PRESSURE RIDGE DOMINATES THE WEATHER PATTERN. THIS RIDGE IS CURRENTLY CENTERED OVER THE MID ATLANTIC STATES AND IS EXPECTED TO WEAKEN AND MOVE EAST TO JUST OFF THE CAROLINA COAST BY 06Z SAT. THIS WEAKENING RIDGE WILL ALLOW A DEVELOPING FRONTAL BOUNDARY.
331 PM CST FRI FEB 19 2016 HIGH PRESSURE EXTENDING ACROSS THE GULF STATES FROM THE ATLANTIC WILL MAINTAIN DRY CONDITIONS THROUGH TONIGHT. OPTIMAL RADIATIONAL COOLING IN COMBINATION WITH SUBTLE RETURN FLOW AROUND THE FRINGE OF THE RIDGE WILL ALLOW FOG FORMATION OVERNIGHT THAT COULD BECOME DENSE IN SOME LOCATIONS IF THE WINDS DO BECOME CALM.
WINDS NORTH OF TAMPA WILL BECOME SOUTHEAST AND DECREASE AS THE CENTER OF HIGH PRESSURE MOVES OFF THE EASTERN SEABOARD.
601 PM EST FRI FEB 19 2016 A WARM FRONT WILL LIFT NORTHEAST THROUGH THE REGION OVERNIGHT AND EARLY SATURDAY.
/ISSUED 600 PM EST FRI FEB 19 2016/ CURRENT SATELLITE LOOP SHOWS MOSTLY CLEAR SKIES ACROSS THE AREA AS HIGH PRESSURE RIDGE DOMINATES THE WEATHER PATTERN. THIS RIDGE IS CURRENTLY CENTERED OVER THE MID ATLANTIC STATES AND IS EXPECTED TO WEAKEN AND MOVE EAST TO JUST OFF THE CAROLINA COAST BY 06Z SAT. THIS WEAKENING RIDGE WILL ALLOW A DEVELOPING FRONTAL BOUNDARY.

408 PM CST FRI FEB 19 2016 PUT OUT A QUICK UPDATE FOR THE SHOWERS NOW MOVING FROM WESTERN INTO CENTRAL NORTH DAKOTA AFFILIATED WITH COMPACT UPPER LOW OVER NORTHWEST NORTH DAKOTA. HAVE EXPANDED THE HIGH WIND WARNING TO COVER WESTERN NORTH DAKOTA SOUTH OF THE MISSOURI RIVER AND WEST OF MORTON COUNTY. LATE THIS EVENING AND OVERNIGHT IT WILL CONTINUE TO BE BREEZY ACROSS THE REGION AS THE COLD PUSH MOVES IN BEHIND THE COLD FRONT AND TS ASSOCIATED PRESSURE RISE. THE TROUGH LOSES MOST OF ITS MOISTURE ACROSS THE ROCKIES BUT SUFFICIENT FOR LIGHT SNOW ACCUMULATIONS STARTING LASE SATURDAY AFTERNOON ACROSS THE NORTH.
/ISSUED 313 PM CST FRI FEB 19 2016/ WEAK COLD FRONT CURRENTLY EXTENDS FROM NE OK TO NEAR WICHITA FALLS. TEMPS BEHIND THIS FRONT IN THE 70S THIS AFTERNOON SO RATHER DIFFICULT TO CALL THIS MUCH OF A COLD FRONT. FIRE WEATHER CONDITIONS WILL BE KEPT DOWN ON SATURDAY DUE TO SLIGHTLY COOLER TEMPS WITH ADDITIONAL CLOUD COVER AND DEWPOINT RISING TO THE UPPER 50S TO NEAR 60. DESPITE THE COOLER TEMPS SATURDAY. COLD FRONT WILL PUSH INTO NORTH TEXAS SATURDAY AFTERNOON.
DRY AND UNSEASONABLY WARM CONDITIONS WILL PREVAIL THIS WEEKEND AND DURING THE UPCOMING WEEK AS HIGH PRESSURE DOMINATES. CLEAR SKIES OR PERHAPS JUST A FEW CIRRIFORM CLOUDS WILL THEN PREVAIL SUN-MON AS THE FLOW ALOFT BECOMES INCREASINGLY NWLY AHEAD OF AN AMPLIFYING UPPER RIDGE NEAR THE WEST COAST. THE HIGHLY AMPLIFIED RIDGE IS PROGGED TO REMAIN QUASI-STATIONARY NEAR THE WEST COAST TUE. THEN THE RIDGE SHOULD FLATTEN SOMEWHAT OOVER THE WRN CONUS WED. GFS/ECMWF WERE FAIRLY SIMILAR WITH DEPICTING THE NEXT AMPLIFYING UPPER TROUGH OVER THE WRN CONUS NEXT THUR-FRI. A FEW SPRINKLES MAY OCCUR ACROSS MAINLY THE HIGHER TERRAIN THROUGH THE EARLY EVENING HOURS TONIGHT.

COLD FRONT WILL PUSH INTO NORTH TEXAS SATURDAY AFTERNOON.
Warm front continues to slowly push northward through NE OK with a marked increase in low level moisture.
THEN SLOWLY ERODE SATURDAY AS THE LOW LEVEL INVERSION RELAXES AND BOUNDARY LAYER WINDS BECOME MORE TROPICAL.
AS THE HIGH SINKS SOUTH EXPECT SURFACE WINDS TO DIMINISH THE REST OF TONIGHT.
THIS WILL CONTINUE TO MAINTAIN A STEADY SUPPLY OF MOISTURE IN THE LOW-LEVELS.
COOL SHOWERY WEATHER WITH LOWERING SNOW LEVELS WILL PREVAIL TONIGHT IN THE WAKE OF A COLD FRONT THAT PASSED BY THIS AFTERNOON.
THE FAST-MOVING UPPER TROUGH IS LIFTING TO OUR NORTH. WEAK HIGH PRESSURE ALOFT WILL BUILD ON SATURDAY FOR DRY WEATHER AND LIGHT WINDS.
PUT OUT A QUICK UPDATE FOR THE SHOWERS NOW MOVING FROM WESTERN INTO CENTRAL NORTH DAKOTA AFFILIATED WITH COMPACT UPPER LOW OVER NORTHWEST NORTH DAKOTA. HAVE EXPANDED THE HIGH WIND WARNING TO COVER WESTERN NORTH DAKOTA SOUTH OF THE MISSOURI RIVER AND WEST OF MORTON COUNTY. LATE THIS EVENING AND OVERNIGHT IT WILL CONTINUE TO BE BREEZY ACROSS THE REGION AS THE COLD PUSH MOVES IN BEHIND THE COLD FRONT AND TS ASSOCIATED PRESSURE RISE. THE TROUGH LOSES MOST OF ITS MOISTURE ACROSS THE ROCKIES BUT SUFFICIENT FOR LIGHT SNOW ACCUMULATIONS STARTING LASE SATURDAY AFTERNOON ACROSS THE NORTH.
556 PM CST FRI FEB 19 2016 Main front/trough has passed through about 2/3 of the forecast area so far this afternoon, and was approaching the I-57 corridor at mid afternoon. A low pressure area will develop in the southern plains Saturday and is forecast to lift northeast and move across southern IL Sat night. Models have finally come into better agreement and even the new ECMWF has trended south with the track of the low.
HIGH PRESSURE WILL BUILD TONIGHT AND MAINTAIN DRY WEATHER THROUGH SATURDAY EVENING.
BUT NOT BE IN THE HIGH WIND WARNING CRITERIA. BUT THE HIGH SUSTAINED WINDS/GUSTS ARE FAIRLY CLOSE. THE BACK EDGE OF THE STRATUS IS IN SOUTHEAST MINNESOTA/NORTHEAST IOWA AND SHOULD CLEAR THE REGION FROM SOUTHWEST TO NORTHEAST IN THE EARLY EVENING AS THE CLOSED LOW QUICKLY PROPAGATES EAST THROUGH THE GREAT LAKES. IT APPEARS THAT MUCH OF THE DAY SHOULD BE SUNNY WITH WARMER LOW LEVEL AIR MAKING IT BACK INTO SOUTHERN WISCONSIN OVERNIGHT. SOME CLOUD COVER MAY MOVE IN FROM THE NORTH AS A MID LEVEL SHORT WAVE TROUGH MOVES THROUGH THE NORTHERN PORTION OF THE STATE.
THEN MUCH LIGHTER WIND AS HIGH PRESSURE REPLACES THE LOW BRIEFLY ON SAT.
/ISSUED 331 PM CST FRI FEB 19 2016/ HIGH PRESSURE EXTENDING ACROSS THE GULF STATES FROM THE ATLANTIC WILL MAINTAIN DRY CONDITIONS THROUGH TONIGHT. OPTIMAL RADIATIONAL COOLING IN COMBINATION WITH SUBTLE RETURN FLOW AROUND THE FRINGE OF THE RIDGE WILL ALLOW FOG FORMATION OVERNIGHT THAT COULD BECOME DENSE IN SOME LOCATIONS IF THE WINDS DO BECOME CALM.
AS THIS LOW APPROACHES. LOW LEVEL ISENTROPIC LIFT WILL INCREASE TO THE EAST OF THE LOW. THIS WILL CAUSE A WARM FRONT TO LIFT NORTH INTO SE KS FOR THE MORNING HOURS. AS THE LOW LAYERS SATURATE. NOT TOO JAZZED ABOUT PRECIP CHANCES WITH THIS LOW. BUT WILL LEAVE THE LOW POPS IN FOR THE DAYTIME ON SAT FOR EXTREME SE KS. AND IS EXPECTED TO LIFT NORTHWARD LATER TONIGHT AS A WARM FRONT IN RESPONSE TO APPROACHING WEAK UPPER LEVEL WAVE.
503 PM MST FRI FEB 19 2016 SOUTHERLY WINDS UP TO 10 MPH EARLY THIS EVENING WILL SHIFT TO THE NORTHWEST AT SIMILAR SPEEDS AFTER MIDNIGHT AS ANOTHER COLD FRONT MOVES THROUGH. HIGH TEMPERATURES SATURDAY A DEGREE OR TWO COOLER COMPARED TO TODAY WITH LOW TO UPPER 60S.
MILD TEMPERATURES WILL CONTINUE THROUGH THE DAY ON SATURDAY AS A COLD FRONT APPROACHES FROM THE NORTHWEST. THE CLOUDS COULD MAKE THE HIGH TEMPERATURE FORECAST A BIT TRICKY.
656 PM EST FRI FEB 19 2016 A WARM FRONT WILL SWEEP THROUGH THE AREA TONIGHT AND TRIGGER LIGHT PRECIPITATION. FREEZING RAIN OR EVEN JUST RAIN. UPR TROF STARTS TO DIG AND COOLER AIR BEGINS TO FILTER IN SUN NGT INTO MON. SHRT WV RONDING THE TROF TRIES TO HOOK UP WITH A SRN STREAM SHRT WV RUNNING THRU THE MID ATLANTIC. SYSTEM MVES OUT EARLY MON AND LEAVES COOLER BUT GNRLY DRY WX. A WEAK LOW PRESSURE MOVING THROUGH THE UPPER GREAT LAKES REGION OVER THE NEXT 24 HOURS WILL BRING SIGNIFICANT WINDY CONDITIONS. SLEET AND FREEZING RAIN WITH A TRANSITION TO THE LATTER AS THE NIGHT WEARS ON.
High pressure building into Illinois behind the departing low pressure system will provide relatively dry air in the low to mid levels. The slightly cooler air north of the cold/stationary front will cause low temps to dip into the upper 30s north of I-74, but readings will remain in the mid 40s south of I-70, just ahead of the cold front. Main front/trough has passed through about 2/3 of the forecast area so far this afternoon, and was approaching the I-57 corridor at mid afternoon. A low pressure area will develop in the southern plains Saturday and is forecast to lift northeast and move across southern IL Sat night. Models have finally come into better agreement and even the new ECMWF has trended south with the track of the low.
740 PM EDT TUE SEP 22 2015 HIGH PRESSURE EXTENDED FROM NEW ENGLAND. AND LOW PRESSURE WAS OVER GEORGIA WITH A TROF TRAILING INTO THE TENNESSEE VALLEY. AS HIGH PRESSURE REMAINS OVER THE NORTHEAST UNITED STATES.
NO CHANGES WERE NEEDED AT THIS TIME AS HIGH PRESSURE REMAINS IN CONTROL. 18Z SFC ANALYSIS SHOWS HIGH PRESSURE IN PLACE OVER THE OHIO VALLEY AND NORTHEAST. THERE WILL BE A SMATTERING OF ENERGY EAST OF KENTUCKY ASSOCIATED WITH A WEAKENING UPPER LEVEL LOW OVER THE SOUTHEAST PARTS OF THE NATION. GIVEN THE MODEL AGREEMENT AND LACK OF ANY SIGNIFICANT FEATURES WILL FAVOR THE HIGHER RESOLUTION HRRR AND NAM12 MODELS FOR WX SPECIFICS IN A REGIME OF PERSISTENCE.
1258 AM EDT WED SEP 23 2015 PLEASANT EARLY FALL WEATHER EXPECTED THROUGH THE END OF THE WEEK AS HIGH PRESSURE BUILDS OVER THE STATE. A DRY COLD FRONT WILL PUSH THROUGH THE AREA TOMORROW BRINGING DRY COOL AIR. DUE TO WARMER TEMPS AND THE CLOUD COVER.

01Z SURFACE ANALYSIS SHOWS WEAK RIDGING ALONG THE COAST AND TROUGHING FROM COT-CLL SO FULLY EXPECT WINDS TO GO CALM ACROSS THE REGION AS ATMOSPHERE DECOUPLES. TOMORROW LOOKS LIKE A NEAR REPEAT OF TODAY BUT PERHAPS A DEGREE OR TWO COOLER AND STILL WELL ABOVE NORMAL. SURFACE HEATING WILL PROMOTE IMPROVEMENT TO VFR AT ALL TERMINALS BY MID- MORNING WITH SURFACE RIDGING PROMOTING LIGHT EASTERLY TO NORTHEASTERLY WINDS 5 TO 10 KNOTS. HUFFMAN ANOTHER UNSEASONABLY WARM DAY ACROSS SOUTHEAST TEXAS WITH HIGH TEMPS IN THE LOWER/MID 90S. SLIGHTLY LOWER DEW PTS SHOULD ALLOW MIN TEMPS TO COOL A DEGREE OR TWO COOLER FROM THIS MORNINGS LOW TEMPS. UPPER LEVEL RIDGING WILL REMAIN THE DOMINANT WEATHER FEATURE ON WEDNESDAY WITH VERY WARM TEMPERATURES ONCE AGAIN.

HIGH PRESSURE WILL BUILD OVER THE NRN MID-ATLANTIC AREA OVERNIGHT AND REMAIN THROUGH THE WEEKEND AS LOW PRESSURE PERSISTS OVER THE SERN STATES. LARGE SCALE PATTERN CHANGES VERY LITTLE WHICH IS PROBABLY WHY MODELS CONTINUE TO STRUGGLE HOW QUICKLY/HOW FAR NORTH MOISTURE IS ABLE TO SPREAD BEGINNING THU NIGHT FROM LOW PRESSURE OFF THE SE COAST. LOWS WILL BE A LITTLE WARMER. ESPECIALLY EAST OF THE BLUE RIDGE.
BUFKIT NAM/GFS BOTH INDICATE AN MOISTENING OF THE LOWER BOUNDARY LAYER LATE TONIGHT THROUGH WEDNESDAY. UPPER LEVEL ANALYSIS PLACES HIGH STRETCHING OVER THE SOUTHERN PLAINS INTO THE MIDWEST WITH TROUGH OVER THE EASTERN PACIFIC. COMPACT UPPER LOW CONTINUES TO SPIN OVER THE FOUR CORNERS AREA.
