Light southerly winds will return today as high pressure shifts to the east.
/ISSUED 1105 AM CDT FRI MAY 1 2015/ MORNING SURFACE ANALYSIS PLACED A WEAK COLD FRONT JUST NORTHEAST OF THE REGION. THIS HIGH PRESSURE RIDGE WILL LINGER ALONG THE COAST THROUGH TONIGHT BEFORE MOVING OFF TO THE EAST ON SATURDAY. THERE WAS ALSO AN UPPER LEVEL LOW PRESSURE TROUGH LOCATED OVER THE COASTAL AREAS THIS MORNING.
449 PM MDT FRI MAY 1 2015 A FLAT RIDGE OF HIGH PRESSURE CONTINUES TO DOMINATE OUR WEATHER PATTERN THROUGH SATURDAY. A LARGE CLOSED LOW OFF OF BRITISH COLUMBIA AND A TROUGH OF LOW PRESSURE NEAR THE BAJA OF CALIFORNIA WILL IMPACT OUR WEATHER DURING THE WORK WEEK.
HIGH PRESSURE WILL BRING DRY CONDITIONS TO NORTHWEST CALIFORNIA THROUGH THE WEEKEND WITH SEASONABLE TEMPERATURES NEAR THE COAST AND INLAND TEMPERATURES ABOVE NORMAL.
405 PM EDT FRI MAY 1 2015 UPPER LEVEL LOW CONTINUES TO EXIT TO THE EAST. HIGH PRESSURE WILL THEN BUILD OVER THE AREA INTO THE WEEKEND. WITH HIGHS TOPPING OUT IN THE LOWER 70S. GEOPOTENTIAL HEIGHTS RISE AND UPPER LEVEL RIDGING BUILDS IN THROUGH THE MIDDLE OF THE WEEK.
135 PM EDT FRI MAY 1 2015 AN UPPER LEVEL LOW PRESSURE SYSTEM MOVES OFF TO THE EAST TODAY.
222 PM EDT FRI MAY 1 2015 LOW PRESSURE WILL PASS WELL TO THE SOUTH THROUGH TONIGHT. A WEAK LOW PRESSURE TROUGH WILL DEVELOP OVER THE AREA ON SATURDAY. AND THEN WEAKEN SATURDAY NIGHT AS HIGH PRESSURE BUILDS FROM THE WEST.
414 PM EDT FRI MAY 1 2015 HIGH PRESSURE WILL REMAIN ACROSS THE REGION TONIGHT THROUGH THE WEEKEND.
232 PM EDT FRI MAY 1 2015 HIGH PRESSURE WILL BRING DRIER AND WARMER WEATHER FOR THE WEEKEND. SO FAR THIS AFTERNOON SHOWER COVERAGE ACROSS THE RIDGES HAS BEEN A BIT LESS THAN EXPECTED. ALTHOUGH A FEW ISOLATED SHOWERS HAVE MANAGED TO DEVELOP WELL AWAY FROM THE RIDGES ACROSS EASTERN OHIO. STILL EXPECT THAT SHOWERS ALONG THE RIDGES WILL LINGER BRIEFLY AFTER SUNSET. WITH HIGHS IN THE MID 60S IN THE HIGHER ELEVATIONS TO AROUND 70 AROUND THE REST OF THE REGION.
255 PM CDT Fri May 1 2015 WV imagery shows an upper level ridge over the SW CONUS, leaving West Texas and Southeast New Mexico under light meridional flow aloft. Overnight, the upper ridge will shift east in response to a trough approaching the west coast, while at the sfc, return flow will begin priming the PBL w/increased moisture.
238 PM EDT FRI MAY 1 2015 HIGH PRESSURE SLOWLY BUILDS TONIGHT INTO THE WEEKEND. HIGH PRESSURE BUILDS FROM THE WEST TONIGHT BRINGING CALM FLOW AND MOSTLY CLEAR SKIES. GOOD MODEL AGREEMENT ON AN UPPER LEVEL HIGH PRESSURE CENTER BUILDING OVER THE SOUTHEASTERN U. UPPER LEVEL RIDGING FROM THIS UPPER HIGH EXTENDING NORTHWARD INTO THE OHIO VALLEY WILL BE THE DOMINATING FACTOR. DEEPER MOISTURE WILL ALSO BE LACKING UNDER THE UPPER RIDGING. WITH A WARMING UPPER RIDGE AND SOUTHERLY LOW LEVEL FLOW TAKING OVER THIS PERIOD.
1228 PM CDT Fri May 1 2015 High pressure is currently over the region bringing clear and quiet weather for the Missouri Ozarks.
NEXT UPPER TROF IS PUSHING THROUGH THE PAC NW. UPPER TROF AXIS WORKS THROUGH THE NRN ROCKIES WITH SFC TROF PUSHING THROUGH THE WRN DAKOTAS. THERMAL RIDGE ALONG WITH DRY W/SW LO LEVEL FLOW WILL HELP PUSH TEMPS INTO THE 80S. COULD SEE SOME AFTN TSTMS ALONG/AHEAD OF THE SFC TROF ACROSS CNTRL SD WHERE MLCAPE UP TO 1000J/KG WILL EXIST.
146 PM EDT FRI MAY 1 2015 LOW PRESSURE JUST OFF THE NORTH CAROLINA COAST WILL MOVE OFFSHORE TONIGHT. A PRESSURE RIDGE CURRENTLY OVER THE MISSISSIPPI RIVER VALLEY WILL SHIFT EASTWARD. TONIGHT WILL COOLER THAN NORMAL WITH CLEARING SKIES ALLOWING FOR GOOD RADIATIONAL COOLING.
348 PM EDT FRI MAY 1 2015 UPPER LEVEL LOW CONTINUES TO EXIT TO THE EAST. HIGH PRESSURE WILL THEN BUILD OVER THE AREA INTO THE WEEKEND. WITH HIGHS TOPPING OUT IN THE LOWER 70S. IF LOWS END UP COOLER WHICH IS CERTAINLY POSSIBLE GIVEN THE DECENT RADIATIONAL COOLING TONIGHT.
CYCLONIC CIRCULATION AROUND THE OLD MID ATLANTIC UPPER LOW CONTINUES TO BRING SOME BKN-OVC CU TO NORTHERN SECTIONS OF THE SOUTHERN APPALACHIAN MOUNTAIN CHAIN. WOULD EXPECT THE LOWER DECKS TO DISSIPATE LATER THIS AFTERNOON LEAVING SOME BKN CEILINGS AROUND 3500-4000 FT THROUGH MUCH OF THE OVERNIGHT BEFORE THIS LAYER SCATTERS OUT. VFR FLIGHT WILL BE THE RULE AS THE OFFENDING UPPER LOW FINALLY MAKES A BREAK FOR THE OPEN WATERS OF THE ATLANTIC.
THIS AFTERNOON A FEW CLOUDS FROM THE BACK SIDE OF THE LOW PRESSURE STATIONED OFF THE COAST OF NC/VA WILL MAKE IT INTO THE CWA. OCCASIONAL GUSTS UP TO 20 KTS ARE POSSIBLE ESPECIALLY IN THE HIGHER TERRAIN. WITH A STRONG RIDGE OF HIGH PRESSURE MOVING SWD INTO THE REGION.
348 PM EDT FRI MAY 1 2015 A WEAK TROUGH HAS SPARKED SOME SPOTTY SHOWERS BUT THESE WILL DIMINISH THIS EVENING. THIS TROUGH MAY SPARK A FEW ADDITIONAL SHOWERS SATURDAY OVER EASTERN ZONES WITH OTHERWISE DRIER AND WARMER CONDITIONS EXPECTED. THE SHOWERS WILL DIMINISH THIS EVENING DUE IN PART TO THE LOSS OF DAYTIME HEATING WITH A CLEARING TREND OVER TIME FROM WEST TO EAST AS THE TROUGH WILL ALSO BE MOVING OFF TO THE EAST. LOWS WILL GENERALLY BE IN THE LOW TO MID 40S. FOR SATURDAY, GENERALLY LOOKING AT SUNNIER, WARMER, AND DRIER CONDITIONS AS DRIER AIR WORKS IN FROM THE WEST. HOWEVER THERE WILL STILL BE THE SLIGHT RISK OF A SHOWER OR TWO OVER EASTERN ZONES DUE TO THE LINGERING TROUGH. ANY ISOLATED SHOWERS DIMINISH QUICKLY SATURDAY EVENING WITH SURFACE RIDGING DEVELOPING OVER THE AREA.
The cold upper low that brought us showers and thunderstorms yesterday has advanced to North Carolina this morning, and will move off the coast this evening. Without the assistance of the upper low, the cu field today should remain scattered and flat enough to preclude shower activity. On Saturday high pressure will come in from the west and will be centered right over Kentucky by evening. Soundings become unstable in the low levels, but mid-level lapse rates are much weaker.
535 PM EDT FRI MAY 1 2015 HIGH PRESSURE WILL BRING DRIER AND WARMER WEATHER FOR THE WEEKEND. MUCH OF THE REGION WILL AGAIN JUMP INTO THE LOWER 70S AS 850 MB TEMPERATURES JUMP PAST 8C.
1212 PM CDT FRI MAY 1 2015 06Z OBJECTIVE ANALYSIS HAS HIGH PRESSURE FROM THE GREAT LAKES INTO THE LOWER MISSISSIPPI VALLEY. QUIET AND DRY CONDITIONS WILL BE SEEN ACROSS THE AREA THIS MORNING AS HIGH PRESSURE SLOWLY DRIFTS INTO THE EASTERN GREAT LAKES.
347 PM EDT FRI MAY 1 2015 LOW PRESSURE WILL PASS WELL TO THE SOUTH THROUGH TONIGHT. A WEAK LOW PRESSURE TROUGH WILL DEVELOP OVER THE AREA ON SATURDAY. AND THEN WEAKEN SATURDAY NIGHT AS HIGH PRESSURE BUILDS FROM THE WEST.

345 PM CDT FRI MAY 1 2015 A BACK DOOR COLD FRONT CURRENTLY LOCATED ALONG A LINE FROM CLARKSVILLE TX. WEATHER SHOULD REMAIN QUIET THROUGH THE REMAINDER OF THE WEEKEND AS UPPER LEVEL RIDGING WILL CONTINUE TO DOMINATE OUR WEATHER.
UPPER TROUGH WILL BEGIN TO SHIFT EAST AND HIGH PRESSURE WILL REMAIN IN CONTROL AT THE SURFACE.
AN UPPER LEVEL TROUGH OVERHEAD IS AIDING IN DEVELOPING SOME HIGH CLOUDINESS TO OUR EAST BUT OVERALL LARGE SCALE SUBSIDENCE IS PRODUCING DRY AND PLEASANT WEATHER ACROSS THE AREA. DEWPOINTS ARE IN THE LOW 60S TO UPPER 0S WITH TEMPERATURES STARTING TO WORK TOWARDS THE MID 80S. MODERATE EASTERLY WINDS PERSIST IN RESPONSE TO RIDGING OVER THE NORTHWESTERN GULF COAST. SURFACE RIDGING WILL NUDGE TO THE EAST JUST A BIT OVER THE GULF DURING THE DAY SATURDAY. WITH LEE TROUGHING INTENSIFYING SLIGHTLY TO OUR WEST IN RESPONSE TO A SLOWLY ADVANCING UPPER TROUGH OVER THE PACIFIC NORTHWEST. BUT OTHERWISE A WARM AND MOSTLY SUNNY DAY IS FORECAST WITH HUMIDITY VALUES STAYING LOWER THAN WE HAVE EXPERIENCED FOR THE PAST FEW WEEKS WITH DEWPOINTS IN THE LOW TO MID 60S.
244 PM CDT FRI MAY 1 2015 A 1022 MB HIGH PRESSURE OVER IL WILL SETTLE INTO THE MID MS AND OHIO RIVER VALLEYS BY SATURDAY MORNING AND CONTINUE FAIR WEATHER OVER CENTRAL AND SOUTHEAST IL INTO SATURDAY.

THE SHOWERS ARE LIMITED DUE TO THE REMAINING DRY AIR IN PLACE AS WELL AS THE WAVE WORKING THROUGH THE GENERAL UPPER LEVEL RIDGING IN PLACE. AND HIGH PRESSURE STILL IN CONTROL OF THE WEATHER. TEMPERATURES WILL CONTINUE TO WARM DURING THE DAY SATURDAY AS A LOW OVER SOUTHERN MANITOBA HELPS TO DRIVE WARMER SOUTH TO SOUTHWESTERLY WINDS INTO THE AREA. THESE WARMER TEMPERATURES WILL ALLOW FOR LAKE BREEZE DEVELOPMENT DURING THE AFTERNOON HOURS WITH THE STRONGEST COMPONENT COMING FROM LAKE MICHIGAN SINCE THE OVERALL FLOW WILL BE FROM THE SOUTH. A MAINLY ZONAL PATTERN WILL PREVAIL THROUGH THE NRN CONUS AS LIGHT SW FLOW DEVELOPS BETWEEN HIGH PRES MOVING INTO THE ERN LAKES AND A TROUGH OVER THE NRN PLAINS.
1230 PM CDT FRI MAY 1 2015 UPDATED AVIATION SECTION FOR 18Z TAF ISSUANCE THE SHORT TERM WILL SEE THE LOW DEPART THE COMMONWEALTH AND HEAD TO THE MID ATLANTIC. WHICH HOLDS ITS HIGH PRESSURE AND RIDGES THRU THE WEEKEND. THIS SHOULD SUPPRESS ANY RELATED/NEARBY POPS CONTAINED AROUND THE RIM OF THE UPPER HIGH THAT DEVELOPS ACROSS THE LOWER MS VALLEY WITH TIME.
LOW TEMPERATURES IN THE LOW TO MID 40S IN FAR EASTERN COLORADO WITH MID 40S TO MID 50S EAST OF THE BORDER.
DRY CONDITIONS BEHIND THIS MORNINGS'S COLD FRONT WILL HELP REINFORCE CLEAR SKIES AND COOLER WEATHER THAT WE EXPERIENCED THIS MORNING. CLOSER TO THE COAST, WARM GULF WATERS WILL KEEP COASTAL AREAS IN THE MID-UPPER 50S WITH INTERIOR FLORIDA COUNTIES SEEING THE LOW 50S.
400 PM EDT FRI MAY 1 2015 HIGH PRESSURE WILL KEEP DRY AND WARM WEATHER IN PLACE THROUGH THE WEEKEND.
RELATIVELY DRY AIR IN THE LOWEST 3000 TO 5000 FT MAKES LOW CIGS LOOK LESS LIKELY TONIGHT BUT WIND SPEEDS MAY FALL ENOUGH IN A FEW PLACES FOR PATCHY FOG DEVELOPMENT. MID TO UPPER LEVEL TROUGH OVERHEAD TO HAVE LITTLE IMPACT ON THE SENSIBLE WEATHER WITH A VERY DRY ATMOSPHERIC COLUMN IN PLACE.
THE RIDGE WILL SLOWLY WEAKEN THIS WEEKEND WITH HIGH TEMPERATURES GRADUALLY LOWERING. HOWEVER HIGHS IN THE ROGUE VALLEY WILL STILL BE ABOUT 10 DEGREES WARMER THAN SEASONAL NORMS. ONSHORE FLOW WILL BRING COOLER AIR TO THE COASTAL ZONES BUT TEMPERATURES THERE WILL STILL REMAIN QUITE WARM.
NORTHWEST FLOW ACROSS AN UPPER RIDGE OUT WEST WILL BRING IN HIGH BASED CLOUDINESS/CEILINGS FOR TONIGHT ACROSS SOME TERMINALS.
342 PM CDT Fri May 1 2015 (Tonight and Saturday) Lee trough will begin to develop Saturday, with southerly winds gradually increasing. Low level moisture return, however, will continue to be lacking and upper ridging will continue to suppress shower or thunderstorm development. Mild temperatures will continue with highs in the lower to mid 80s and lows in the 50s.
WARMER THAN NORMAL THROUGH THE WEEKEND WITH A SLIGHT COOLING TREND BACK TO NORMAL AFTER THAT.

DRY WEATHER WILL CONTINUE THROUGH SUNDAY AS THE FLAT UPPER RIDGE SLOWLY MOVES ACROSS THE PACIFIC NW AND THE ROCKIES.
UPPER TROUGH CURRENTLY STRETCHES FROM THE UPPER MISSISSIPPI VALLEY INTO THE SOUTHERN HIGH PLAINS. AT THE SURFACE A COLD FRONT STRETCHES FROM THE WESTERN GREAT LAKES. HIGH PRESSURE WILL REMAIN SITUATED OVER THE CENTRAL PLAINS PROVIDING PLENTY OF SUN AND SEASONAL TEMPS. THE PROGRESSIVE NATURE OF THIS TROUGH SHOULD LIMIT ANY KIND OF WIDESPREAD HEAVY RAINFALL EVENT. EVEN THOUGH SOME COOLER AIR WILL SPILL SOUTH MID WEEK BEHIND THE DEPARTING WAVE. IT STILL LOOKS LIKE TEMPS WILL BE CLOSE TO OR A FEW DEGREES COOLER THAN SEASONAL READINGS.
215 PM EDT SAT OCT 24 2015 COLD FRONT MOVES THROUGH OVERNIGHT. STRONGER LOW PRESSURE AND COLD FRONT MID WEEK. MODELS SHOWING A GOOD BAND OF LIFT ALONG AND IN ADVANCE OF THE COLD FRONT THAT MOVES THROUGH OVERNIGHT. ONCE THE COLD FRONT CLEARS THE MOUNTAINS.
