HIGH TEMPERATURES WILL RANGE FROM THE 60S IN SOUTHERN MICHIGAN TO THE LOWER 80S ALONG THE OHIO RIVER. LOWS TONIGHT WILL RANGE FROM THE LOWER 50S IN SOUTHERN MICHIGAN TO NEAR 60 ALONG THE OHIO RIVER. UPPER LEVEL RIDGING WILL BE UNDERWAY AT THE START OF THE PERIOD WITH SURFACE FRONTAL BOUNDARY LIKELY ALREADY ON ITS WAY NORTH INTO LOWER MICHIGAN (IF NOT ALL READY THERE).
EASTERLY LOW LEVEL FLOW THIS AM WILL PERPETUATE THE LOW DEWPOINT AIRMASS WITH ONLY HIGH CLOUDS TO INHIBIT HEATING. WARMER TEMPS AND LOWER AFTERNOON RH. THERE IS SOME EVIDENCE OF A TROWAL FEATURE LINGERING INTO LATE WEDNESDAY AS THE UPPER TROF MOVES OVERHEAD.
THE RIDGE OF HIGHER PRESSURE SHOULD HOLD ITS POSITION THROUGH THE SHORT TERM WITH A FAIR AMOUNT OF WARM AIR ALOFT WHICH SHOULD LIMIT ANY SHOWER OR THUNDERSHOWER DEVELOPMENT TO HIGHER TERRAIN LOCALES ACROSS THE FORECAST AREA. UPPER LEVEL RIDGE CONTINUES ACROSS THE SOUTHEAST AND FORECAST AREA THROUGH THE END OF THE WEEK AND INTO THE WEEKEND. HIGHS AND LOWS WILL NOT VARY MUCH REACHING THE UPPER 70S TO MID 80S FOR HIGHS IN THE LOWER ELEVATIONS WITH LOWS AT NIGHT IN THE 50S TO MID 60S INTO THE WEEKEND.
BERMUDA HIGH PRESSURE WILL EXTEND INTO OUR REGION THROUGH MID WEEK. AN AREA OF LOW PRESSURE WILL FORM NEAR THE BAHAMAS AND MEANDER OFF THE SOUTHEAST COAST DURING THE MIDDLE OF THE WEEK. HIGH PRESSURE WILL CONTINUE TO RIDGE WESTWARD INTO CENTRAL NC. EVEN AS THE HIGH SHIFTS OFFSHORE. WITH HIGH PRESSURE OVER THE NE U. THE BIGGER FEATURE WILL BE THE CLOSED LOW DEVELOPING OFF THE EAST FLORIDA COAST. EXPECT HIGHS IN THE LOW TO MID 80S. LOWS WILL BE A FEW DEGREES WARMER THAN PREVIOUS NIGHTS. THERE IS HIGH CONFIDENCE IN THE OVERALL PATTERN OF UPPER LEVEL RIDGING OVER THE EASTERN UNITED STATES LATE THIS WEEK THROUGH THE WEEKEND. THE TROUGHING OUT WEST. MODELS STILL LIKELY DO NOT HAVE A GOOD HANDLE ON THE EVOLUTION OF THE POTENTIAL COASTAL STORM THAT WOULD DEVELOP UNDER THE RIDGE.
318 PM EDT TUE MAY 5 2015 A COLD FRONT WILL SLIDE ACROSS THE REGION TONIGHT FROM CANADA.
358 PM CDT TUE MAY 5 2015 SUBTLE WARM FRONT CREEPING NORTHWARD ACROSS THE AREA.
316 PM EDT TUE MAY 5 2015 A LOW PRESSURE SYSTEM IS EXPECTED TO FORM NEAR THE BAHAMAS WEDNESDAY. WITH MOSTLY CLEAR SKIES AND LIGHT WINDS THINK A BLEND TOWARD THE COOLER MET NUMBERS WILL WORK TONIGHT.
255 PM EDT TUE MAY 5 2015 A WARM FRONT WILL MOVE NORTH OF THE REGION TONIGHT WITH RAIN CHANCES IN THE FORECAST INTO WEDNESDAY. KEPT HIGHEST POPS NORTH OF THE I-80 CORRIDOR TONIGHT AS WARM FRONT PUSHES NORTHEAST ACROSS REGION. ONLY SCATTERED SHOWERS HAVE DEVELOPED NEAR THE SOUTHEAST RIDGES SO THIS AFTERNOON AND EXPECT ONLY SCATTERED DEVELOPMENT SOUTH OF I-80 THIS EVENING. UPPER LEVEL RIDGE WILL BUILD ACROSS REGION THROUGH THE PERIOD WITH WARM TEMPERATURES AND ONLY SPOTTY. MAINLY DIURNAL SHOWERS OR ISOLATED STORMS ESPECIALLY ALONG THE RIDGES. UPPER RIDGE REMAINS IN CONTROL THROUGH THE WEEKEND WITH WARM TEMPERATURES.
319 PM CDT TUE MAY 5 2015 A WARM FRONT REMAINS DRAPED ACROSS EASTERN NEBRASKA AND WESTERN IOWA THIS AFTERNOON WITH A FEW ISOLATED SHOWERS AROUND THE BOUNDARY ACROSS NORTHEAST NEBRASKA. A MID LEVEL NEGATIVELY TILTED TROUGH AXIS EXTENDS ACROSS THE FOUR CORNERS AREA INTO NORTHEASTERN NEW MEXICO. THIS WAVE WILL CONTINUE TO MOVE NORTHEAST OVERNIGHT BRINGING INCREASING SHOWERS AND THUNDERSTORMS TO THE HIGH PLAINS.
WEAK SHORT WAVE TROUGH ENHANCED BY WHAT APPEARS TO BE AN EMBEDDED MESOSCALE CONVECTIVE VORTICITY WAS SPINNING THROUGH IA OVERNIGHT RESULTING IN WIDESPREAD SHOWERS AND EMBEDDED THUNDERSTORMS. TREND HAS BEEN FOR LESS AND LESS ACTION ALONG THE NORTHWARD MOVING AND WEAKENING WARM FRONT. ACTIVE WEATHER PATTERN ON TAP WITH SEVERAL DISTURBANCES MOVING THROUGH THE REGION OUT OF THE MEAN LONG WAVE TROUGH OVER THE WESTERN CONUS.
HIGHS ARE EXPECTED TO REACH INTO THE LOW/MID 80S ONCE AGAIN THIS AFTERNOON. SFC WINDS REMAIN LIGHT AND OUT OF THE E/SE THANKS TO THE RIDGE IN THE ATLANTIC.
AIRMASS WILL BE WARMER AND DRIER ON WEDNESDAY. COULD BE A BETTER CHANCE OF A FEW THUNDERSTORMS IN THE AFTERNOON WITH THE WARMER TEMPERATURES AND THE REMAINING LOW LEVEL MOISTURE.
TEMPERATURES SHOULD GENERALLY REACH THE LOW TO MID 80S TOMORROW AFTERNOON. LOWS WILL DIP INTO THE MID 50S IN THE VALLEYS AND NEAR 60 ON THE RIDGES.
AN UPPER LEVEL TROUGH OVER PACIFIC NORTHWEST WILL BRING INCREASINGLY MOIST AND UNSTABLE SOUTHWEST FLOW ALOFT OVER MONTANA.
500MB LOW/TROUGH ACROSS THE SOUTHWEST UNITED STATES THIS AFTERNOON WILL LIFT SLOWLY NORTHEAST TONIGHT INTO WEDNESDAY.
With regards to the low pressure system we've been watching over the past couple days, forecast models continue to dig this feature further south and west into northern California.
129 PM EDT TUE MAY 5 2015 A WEAKENING COLD FRONT WILL BECOME STATIONARY OVER THE AREA TODAY. THE FRONT WILL LIFT BACK NORTH AS A WARM FRONT ON WEDNESDAY.
THE FORECAST AREA CONTINUES IN THE WESTERN PERIPHERY OF HIGH PRESSURE OVER THE ATLANTIC. AS THE UPPER RIDGE BUILDS OVER THE EAST COAST. THEN AS THE WESTERN TROUGH SHIFTS INTO THE PLAINS. AS THE UPPER TROUGH SHIFTS INTO THE PLAINS. HIGH PRESSURE OVER THE AREA CONTINUES TO KEEP THE TAF SITES DRY.
249 PM EDT TUE MAY 5 2015 HIGH PRESSURE OFF THE MID ATLANTIC COAST WILL CONTINUE TO BRING GENERALLY CLEAR SKIES THROUGH TONIGHT.
WE WILL ALSO SEE HEIGHT FALLS IN RESPONSE TO THE UPPER LEVEL TROF MOVING INTO THE PACIFIC NORTHWEST. LATEST WATER VAPOR LOOP WAS SHOWING THE UPPER LEVEL LOW SPINNING OVER NORTHWEST NEW MEXICO. THIS UPPER LEVEL LOW IS DRAWING IN COPIOUS AMOUNTS OF MOISTURE FROM THE SOUTHEAST WITH RAINFALL OCCURRING ACROSS MUCH OF NORTHEAST COLORADO.
1232 PM CDT TUE MAY 5 2015 FOR 18Z TAFS /ISSUED 931 AM CDT TUE MAY 5 2015/ HIGH PRESSURE AND DRY AIR WILL CONTINUE TO DOMINANT OUR WEATHER TODAY. CURRENTLY THE AREA OF HIGH PRESSURE IS LOCATED DIRECTLY OVER THE TENNESSEE VALLEY. KTW HIGH PRESSURE ACROSS THE REGION WILL CONTINUE TO BRING VFR WEATHER ACROSS THE AREA THROUGH WEDNESDAY MORNING.
MID AND UPPER RIDGE HOLDS IN PLACE WITH WEAK STEERING FLOW. WEAK SYNOPTIC FLOW UNDER MID AND UPPER RIDGE. SO CONTINUE WITH THE HIGHER CHANCE POPS THERE. THE 700 MB RIDGE CENTER TO OUR E TRIES TO GIVE A WEAK E FLOW INTO SW VA. UPPER RIDGE STILL IN CONTROL. BEST FORCING WILL BE FROM THE ELEVATED HEAT SOURCES IN THE HIGHLANDS OF THE EASTERN CWA WHILE THE BULK OF THE CWA REMAINS DRY. DEWPOINTS WILL CREEP INTO THE LOW 60S. SO THIS WILL RAISE THE LOWER LIMIT ON THE OVERNIGHT MINIMUM TEMPERATURES THROUGH THE PERIOD. UPPER RIDGE REMAINS IN CONTROL. CANNOT RULE OUT SOME CONVECTION FIRING ON THE EASTERN SIDE OF THE RIDGE. COLD FRONT APPROACHING LATE IN THE PERIOD.
343 PM CDT TUE MAY 5 2015 AIRMASS RECOVERY CONTINUES TO MAKE PROGRESS THIS AFTERNOON AS TEMPERATURES HAVE WARMED INTO THE LOW 70S ACROSS THE WESTERN AND SOUTHERN SOUTH PLAINS. EXPECT STORMS TO CONTINUE THROUGH THIS EVENING AS THE PREVIOUSLY MENTIONED UPPER TROUGH MOVES THROUGH THE SOUTH PLAINS INTO THE TEXAS PANHANDLE. BUT COULD STILL SEE LINGERING SHOWERS/STORMS WITH ONSET OF THE LOW LEVEL JET AND PLENTY OF MOISTURE ACROSS THE ROLLING PLAINS.
A LOW PRESSURE SYSTEM OVER NORTHERN ARIZONA WILL MOVE EAST INTO THE SOUTHERN AND CENTRAL ROCKIES THIS EVENING.
SOUTHEAST TO NORTHWEST ORIENTATED UPPER LEVEL RIDGE AXIS MOVING EAST ACROSS THE NORTHERN PLAINS. WITH A STRONG UPPER LEVEL S/WV TROUGH LIFTING SLOWLY NORTHEAST INTO THE CENTRAL ROCKIES.
631 PM EDT TUE MAY 5 2015 A LOW PRESSURE SYSTEM IS EXPECTED TO FORM NEAR THE BAHAMAS WEDNESDAY. WITH MOSTLY CLEAR SKIES AND LIGHT WINDS THINK A BLEND TOWARD THE COOLER MET NUMBERS WILL WORK TONIGHT.
PRECIP SHOULD END EARLY THIS EVENING AS THE DISTURBANCE THAT MOVED INTO THE AREA FROM THE EAST MERGES WITH THE UPPER TROUGH. CAN'T REALLY FIND A SFC TRIGGER AND UPPER LEVEL WINDS ARE LESS DIVERGENT TOMORROW BUT WILL MAINTAIN CHANCE POPS OUT WEST DUE TO THE HIGHER MOISTURE CONTENT. UPPER LEVEL RIDGING OVER THE GULF AMPLIFIES INTO SE TX THU-SAT WITH A SERIES OF UPPER LEVEL DISTURBANCES PASSING WELL TO THE WEST OF THE CWA.
HIGHS TODAY SHOULD REACH THE LOWER TO MIDDLE 80S. HIGH PRESSURE BEGINS TO BUILD BACK INTO THE REGION LATER TONIGHT, SOUTHERLY WINDS PUSHING THE FRONT BACK TO THE NORTH AND OUT OF THE FORECAST AREA THROUGH WED NIGHT.
HIGH PRESSURE OFF THE EASTERN CONUS WILL KEEP OUR AREA IN AN EASTERLY FLOW REGIME THROUGH TONIGHT. THIS TROUGH WILL CONTINUE WESTWARDS THROUGH THE EVENING AND THE VERY SMALL RAIN CHANCES WILL DIMINISH AFTER SUNSET WITH LOSS OF DAYTIME HEATING. DRYING MID-LEVELS OVERNIGHT (PARTIALLY IN RESPONSE TO A DEVELOPING SUB-TROPICAL LOW OFF THE FLORIDA COAST) WILL YIELD MOSTLY CLEAR SKIES AND NIGHTTIME TEMPS IN THE LOW 60S.
KTW /ISSUED 1232 PM CDT TUE MAY 5 2015/ HIGH PRESSURE ACROSS THE REGION WILL CONTINUE TO BRING VFR WEATHER ACROSS THE AREA THROUGH WEDNESDAY MORNING. RSB /ISSUED 931 AM CDT TUE MAY 5 2015/ HIGH PRESSURE AND DRY AIR WILL CONTINUE TO DOMINANT OUR WEATHER TODAY. CURRENTLY THE AREA OF HIGH PRESSURE IS LOCATED DIRECTLY OVER THE TENNESSEE VALLEY.

258 PM EDT TUE MAY 5 2015 LOW PRESSURE WILL CONTINUE TO PUSH NORTH AND AWAY FROM THE AREA THIS WEEK. SFC LOPRES TROF OVER NRN BAHAMAS HAD FLARE UP OF CONVECTION NEAR IT THIS AFTERNOON. THE LOW WILL CONTINUE TO MOVE NORTH AND AWAY FROM SOUTH FLORIDA OVER THE NEXT SEVERAL DAYS.
133 PM EDT TUE MAY 5 2015 A WARM FRONT WILL WILL KEEP RAIN CHANCES IN THE FORECAST INTO WEDNESDAY. KEPT HIGHEST POPS ALONG THE I-80 CORRIDOR INTO TONIGHT AS WARM FRONT PUSHES NORTHEAST ACROSS REGION. UPPER LEVEL RIDGE WILL BUILD ACROSS REGION THROUGH THE PERIOD WITH WARM TEMPERATURES AND ONLY SPOTTY. MAINLY DIURNAL SHOWERS OR ISOLATED STORMS ESPECIALLY ALONG THE RIDGES. UPPER RIDGE GETS SLOWLY DISLODGED WITH TIME AS ENERGY EJECTS FROM WESTERN U.
With potentially cooler air north and east of the triple point, and evapotranspiration adding moisture into the "dry" air, it's going to be difficult to pinpoint other areas of CI other than the aforementioned mountains and along the dryline.
AN UPPER TROUGH WILL DIVE SOUTH OVER CALIFORNIA THIS WEEK HOWEVER CONDITIONS WILL REMAIN MOSTLY DRY WITH ONLY A FEW ISOLATED SHOWERS OVER THE INTERIOR MOUNTAINS. A WEAK FRONT HAS MOVED INLAND LEAVING DRIER AND COOLER AIR OVER NORTHWEST CALIFORNIA. TEMPERATURES TONIGHT ARE EXPECTED TO BE A COUPLE OF DEGREES COOLER THAN LAST NIGHT. MAY REACH FREEZING BUT CONFIDENCE IS NOT HIGH ENOUGH TO GO WITH A FREEZE WARNING AT THIS TIME.
BUT DOES APPEARS A CLEARING LINE WILL MOVE THROUGH FROM SW TO NE PROVIDING SEVERAL HOURS FOR SOME MODEST RECOVERY IN TEMPS AND SERLY WIND FIELDS AS THE MAIN TROUGH AXIS SWEEPS ACROSS THE AREA BETWEEN 21Z AND 3Z. WE BELIEVE THIS MEANS CONVECTION WILL DEVELOP ACROSS SWRN ZONES AND SPREAD NE ACROSS THE REGION DURING THIS TIME FRAME W/ THE ASSOC DRY LINE PROVIDING THE LOW LEVEL FOCUS. OWING TO MODERATELY STRONG DYNAMICS EMERGING FROM MID-LEVEL TROF.
342 PM EDT TUE MAY 5 2015 UPPER LEVEL RIDGE WILL CONTINUE TO DOMINATE THE FORECAST AREA IN THE SHORT TERM. EVEN WITH THE DEVELOPMENT AND LOCATION OF AN AREA OF LOW PRESSURE DEVELOPING JUST OFF THE EAST COAST OF FL ON WEDNESDAY. WITH THE LOCATION OF THE RIDGE OVER THE REGION. INSTABILITIES DO INCREASE TODAY AND WEDNESDAY ACROSS THAT AREA BUT NOTHING MAJOR WITH HIGH PRESSURE KEEP THINGS SUBDUED. 01 INITIAL CONCERN IS THE EXPECTED DEVELOPMENT OF AN AREA OF LOW PRESSURE SYSTEM OFF THE EAST COAST OF FLORIDA ON WEDNESDAY.
THE TROUGH THAT SITS OVER THE GULF SHOULD BEGIN TO PUSH EAST. AS THE UPPER LEVEL TROUGH PUSHES EAST.
THE ASSOCIATED COLD FRONT IS NOT EXPECTED TO DRIFT INTO WESTERN KANSAS UNTIL LATE WEDNESDAY NIGHT. HIGHS ON WEDNESDAY WILL BE THE WARMEST WEST OF THE DRYLINE AND IN THE LOW TO MID 80S, WITH UPPER 70S TO AROUND 80 EAST.
The synoptic warm front was across eastern Nebraska early this morning with an outflow boundary across eastern Kansas. The upper low over the desert southwest early this morning is forecast by all the models to move northeast today and tonight as another upper trough digs south in the western CONUS.
322 PM CDT TUE MAY 5 2015 CLOSED UPPER LOW LIFTING NORTHEAST OUT OF THE SOUTHWESTERN STATES INTO THE CENTRAL ROCKIES BY TONIGHT. THIS CLOSED UPPER LOW WEAKENS INTO AN OPEN WAVE AS IT TRACKS NORTH AND EAST INTO THE NORTHERN AND CENTRAL PLAINS STATES WEDNESDAY.
RIDGING SHOULD SUPPRESS CONVECTION TODAY KEEPING THE CU FEW AND FAR BETWEEN IN THE VALLEY WITH A PATCH OF AC DRIFTING WEST OFF THE APPALACHIAN SPINE AT TIMES.
FORECAST AREA IS SITTING IN BETWEEN TWO UPPER LOWS. AS THIS ENERGY SHIFTS EASTWARD LATE TONIGHT A COLD FRONT WILL PUSH THROUGH THE AREA ENHANCING LIFT AND SPREADING PRECIPITATION INTO SOUTHEAST MONTANA.
A TROUGH OF LOW PRESSURE EXTENDS FROM THE NORTHWEST BAHAMAS INTO THE FLORIDA STRAITS SOUTHEAST OF THE FLORIDA KEYS.
RIDGE EXTENDS ACROSS THE CENTRAL/SOUTHERN HIGH PLAINS WITH THE LOW STACKED UNDER THE UPPER CIRCULATION. BOTH GFS AND ECMWF AGREE ON ANOTHER INTENSE TROUGH DIGGING OVER THE DESERT SOUTHWEST SUN AFTERNOON INTO SUN NIGHT. PRIOR TO THE 12Z RUNS OF THE ECMWF AND GFS THERE WAS CONSIDERABLE DISAGREEMENT BETWEEN THE TWO MODELS WITH REGARDS TO THE PROGRESSION OF THE UPPER LOW AS IT TRACKED ACROSS THE SOUTHERN/CENTRAL PLAINS. BOTH MODELS HAVE THE UPPER LOW CENTERED ALONG THE KS/OK BORDER BY 12Z WED AND OVER FAR EASTERN KS BY WED EVENING. THE PRESSURE GRADIENT WILL CONTINUE TO DECREASE AS HIGH PRESSURE MOVES INTO THE REGION. WINDS WILL BECOME LIGHT OVERNIGHT AND BECOME SOUTH TO SOUTHWESTERLY FRIDAY AS HIGH PRESSURE MOVES EAST OF THE REGION.
VFR FOR TONIGHT INTO TOMORROW UNDER THE EFFECTING OF SURFACE RIDGING. 08 BEHIND A COLD FRONT. LOOK FOR A PERIOD OF COOLER AND DRIER CONDITIONS FOR TONIGHT THROUGH THE WEEKEND.
256 PM CST THU NOV 12 2015 HIGH PRESSURE CONTINUES TO BUILD INTO THE REGION IN THE WAKE OF THE OVERNIGHT COLD FRONT.
Expect clear skies across the board later tonight, as the upper low gradually opens up and lifts out. Have favored the warmer GFS MOS for max temps, as forecast soundings support mid/upper 50s in the face of raw model surface temps in the lower 50s. Surface dewpoints will likely mix down into the lower 20s, resulting in borderline critical RH values across south-central Kentucky, where wind thresholds are less likely to be met. More favorable radiational cooling conditions Fri night, so temps will be cooler and less uniform. Favored the cooler end of guidance here, and could see some of our typical cold spots dip well into the 20s.
1229 PM EST THU NOV 12 2015 A COLD FRONT WILL CROSS THE REGION THIS AFTERNOON WITH GUSTY WINDS. COLD FRONT ADVANCING INTO EASTERN OHIO AND WILL ACCELERATE ACROSS REGION THIS AFTERNOON. MAINLY NORTHERN TIER AND RIDGES. THE FIRST TO CHANGE WILL BE THE HIGHEST RIDGE TOPS AND THEN THE FAR NORTH.
