OVERNIGHT UPPER LVL TROUGH TO THE NORTH WILL MOVE FURTHER EASTWARD. SHIFTING JET STREAK THAT WAS OVER THE REGION FURTHER SOUTH AND EAST OF SOUTH TEXAS BEFORE THE COLD FRONT MOVES SOUTH SUNDAY MORNING. OVERNIGHT TONIGHT CLOUD COVER AND HIGHER MOISTURE WILL MAKE FOR SLIGHTLY WARMER LOWS IN THE 60S. AS COOLER AIR LAGS BEHIND THE FRONT TOMORROW.
935 PM EDT SAT MAR 26 2016 HIGH PRESSURE WILL SHIFT EAST FROM NEW ENGLAND THROUGH SUNDAY.
CLOUDS RETURN TONIGHT ACROSS MOST AREAS AS LOW LEVEL MOISTURE INCREASES AHEAD OF AN APPROACHING COLD FRONT FROM THE NORTH. SLIGHT CHANCES OF RAIN ARE EXPECTED ALONG AND BEHIND THE COLD FRONT AS IT PUSHES TO THE SOUTH. THE COLD FRONT IS EXPECTED TO ARRIVE AROUND 7 AM ACROSS THE NORTHERN PORTION OF THE HILL COUNTRY AND ALONG THE I-35 CORRIDOR AROUND 10 AM CDT SUNDAY. IN THE WAKE OF THE COLD FRONT.
1029 PM EDT SAT MAR 26 2016 HIGH PRESSURE AND A DRY AIRMASS WILL MOVE NORTHEAST TONIGHT. STRENGTHENING LOW PRESSURE TRAVELING TO INDIANA ON SUNDAY WILL DRAG A COLD FRONT ACROSS THE AREA SUNDAY NIGHT.

REACHING FROM THE GREAT LAKES TO THE LOWER MISSISSIPPI VALLEY THEN OUT OVER THE GULF WHILE THE FRONT ON THE GULF COAST AND SOUTHEAST U. THE ATLANTIC HIGH CONTINUES TO RIDGE ACROSS FL BUT BEGINS TO SLIDE EAST. UPPER-LEVEL TROUGH SWINGS BY TO THE NORTH SUNDAY NIGHT.
THIS QUICK TRANSITION FROM RAIN TO SNOW SHOULD CONTINUE SO NOT EXPECTING SLEET OR FREEZING RAIN TO BE A PROBLEM. CLOSER TO THE BASE OF THE TROUGH PASSAGE.
RIDGING MOVES IN BY SUNDAY AND THIS WILL LEAD TO ANOTHER DRY WITH MILD TEMPERATURES. WINDS WILL INCREASE OVER THE UPPER YELLOWSTONE AND UPPER STILLWATER RIVER VALLEYS TONIGHT AS THE SHORT RANGE MODELS DEVELOP A LEE TROUGH.
MESO HIGH PRESSURE DOMINATED THE FL PENINSULA THIS AFTN/EVENING WHICH WAS INITIALIZED WELL BY THE NAM12. AS PRECIP DRIFTED UNDER THIS LOW LEVEL HIGH EROSION OCCURRED. ADDITIONAL MORE SCATTERED CONVECTION DUE TO SEA BREEZE/OUTFLOW FORCING WAS DRIFTING NNE ALONG AND EAST NEAR THE LOWER ST JOHNS RIVER BASIN FROM MARION TO FLAGLER COUNTY. WAVES OF RAINFALL WILL CONTINUE TO GRADUALLY EDGE EASTWARD FROM THE FL PANHANDLE AND ACROSS THE FORECAST AREA BUT KEPT RAIN CHANCES ONLY IN THE 20-50% RANGE FOR MUCH OF THE NIGHT GIVEN THE INFLUENCE OF THE LOW LEVEL RIDGE. ADVERTISED RAIN CHANCES TRANSITIONING FROM NE FL THIS EVENING TO BACK OVER SE GA THROUGH SUNRISE WHERE LOW LEVEL CONVERGENCE ALONG THE LIFTING TROUGH AXIS WILL BE OVERRIDDEN BY MID LEVEL SHORT WAVE TROUGH ENERGY WHICH WAS GENERATING CONVECTION OVER THE N-CENTRAL GULF OF MEXICO THIS EVENING.
A WARM FRONT MOVING NORTHWARD FROM THE GULF COAST SHOULD BRING SHOWERS AND THUNDERSTORMS TO LOCATIONS SOUTH OF A LINE FROM KLFK. STRONG TO SEVERE CONVECTION IS EXPECTED TO DEVELOP AHEAD OF AN ADVANCING COLD FRONT OVER SOUTHWEST OKLAHOMA/NORTH TEXAS WHICH SHOULD BE MOVING INTO AREAS NORTH OF INTERSTATE 30 AROUND SUNRISE AND SHOULD ALSO BE DECREASING IN INTENSITY. REDEVELOPMENT IS EXPECTED ALONG THE LENGTH OF THE COLD FRONT DURING SUNDAY AFTERNOON.
WILL HOLD ONTO THE LOW SHOWER CHANCES LATER TONIGHT GIVEN LOW CONFIDENCE IN DEVELOPMENT. A WARM FRONT WILL LIFT NORTH BY MIDDAY TO EARLY SUNDAY AFTERNOON, LIFTING CIGS ABOVE 030AGL (VFR).

701 PM EDT SAT MAR 26 2016 A DRY AIR MASS ASSOCIATED WITH HIGH PRESSURE WILL BRING TRANQUIL WEATHER THROUGH THE REMAINDER OF THE WEEKEND.
This means that an area of rain should develop and move into the western CWA either late tonight or early tomorrow morning, depending on how quickly the cold front progresses southeastward. A few models depicted an elongated area of weak H85-H7 moisture convergence stretching into the CWA after 09z, but elevated thunderstorms seem unlikely attm given the low values of MUCAPE. Overnight lows should be warmer than last night due to a warmer start to the day, increasing clouds overnight, and persistent southeasterly to southerly flow ahead of the front.
TEMPERATURES ON THE BACKSIDE OF THE SYSTEM ARE MORE OF A MODIFIED PACIFIC AIRMASS AS OPPOSED TO CANADIAN AND EXPECT READINGS MAINLY AT OR ABOVE FREEZING. COOLEST TEMPERATURES LIKELY IN THE FAR WEST WHERE THERMAL TROF EXISTS AND SOME CLEARING MAY BE POSSIBLE TOWARD DAYBREAK. THE UPPER TROUGH IS EXPECTED TO BE MID-WAY THROUGH THE STATE AT 18Z WITH PRECIP EXITING ALL BUT THE FAR SOUTHEAST. BY 00Z THE TROUGH AXIS AND PRECIP WILL DEFINITELY BE EAST OF THE CWA AND LIKELY THE STATE. TEMPS WILL BE A BIT COOLER WITH THE FROPA BUT SKIES WILL CLEAR AND OVERALL.

153 PM EDT SAT MAY 9 2015 A LARGE AREA OF HIGH PRESSURE REMAINS OVER THE WESTERN ATLANTIC THIS WEEKEND. LOW PRESSURE.
AS THE UPPER LOW CONTINUES IT TRACK INTO THE CENTRAL PLAINS. CURRENT THOUGHT IS THAT MORNING CONVECTION SHOULD PUSH EAST AND NORTHEAST SUFFICIENTLY EARLY THAT THE AIRMASS TO THE EAST OF THE DRYLINE WILL RECOVER SUFFICIENTLY THAT ADDITIONAL THUNDERSTORM DEVELOPMENT WILL OCCUR DURING THE AFTN HOURS FROM THE HIGH PLAINS BACK SOUTH INTO THE OKLAHOMA AND TEXAS PANHANDLES. APPEARS THAT WESTERN/NORTHWESTERN HALF OF THE OKLAHOMA WILL HAVE THE HIGHEST POTENTIAL FOR THESE MOST SEVERE STORMS. LATE NIGHT REDEVELOPMENT LOOKS POSSIBLE ACROSS PORTIONS OF THE AREA AND THEN AGAIN SUNDAY AFTERNOON ALONG AN ADVANCING COLD FRONT.
501 PM EDT SAT MAY 9 2015 A COLD FRONT WILL SLOWLY SAG SOUTH FROM SOUTHERN CANADA TONIGHT AND SUNDAY.

PATCHY FOG IS EXPECTED THIS MORNING WITH THE LOW LEVEL MOISTURE NOW IN THE AREA.
/ISSUED 1112 AM CDT SAT MAY 9 2015/ ADJUSTED POPS FOR THE REMAINDER OF THE DAY BASED ON CURRENT RADAR TRENDS AND THE THINKING THAT MID/UPPER RIDGE NOTED ON WATER VAPOR IMAGERY SHOULD KEEP ATMOSPHERE A LITTLE MORE CAPPED. /ISSUED 356 AM CDT SAT MAY 9 2015/ CURRENTLY TEMPERATURES ARE WARM IN THE LOW TO MID 70S WITH A SOUTHERLY WIND AND CONSIDERABLE CLOUD COVER KEEPING THE TEMPERATURES UP. THE UPPER LOW OVER THE SOUTHWEST U.
133 PM EDT SAT MAY 9 2015 A COLD FRONT OVER THE CENTRAL GREAT LAKES WILL STALL NEAR LAKE ERIE BY SUNDAY.
00Z MODELS ARE IN GOOD AGREEMENT THAT THIS LOW WILL MOVE NORTHEAST ACROSS SOUTHERN LOWER MICHIGAN. 00Z MODELS ARE SHOWING THAT A SHORT WAVE TROUGH WILL THROUGH THE AREA DURING THE EARLY TO MID MORNING. THE MODELS CONTINUE TO STRUGGLE ON HOW FAR NORTH THE WARM FRONT WILL GET. MANY OF THE MODELS SUGGEST THAT THE WARM FRONT WILL LIFT TO NEAR THE MINNESOTA/IOWA BORDER DURING THE EVENING. THERE WILL BE THE POTENTIAL FOR ELEVATED SUPER CELLS NORTH OF THE WARM FRONT. WITH THE SURFACE WINDS BECOMING SOUTHEAST ALONG THE WARM FRONT.
239 PM CDT Sat May 9 2015 An upper level low has moved over the four corners region today pushing the dryline well to the east and leaving very dry air across the entire area today as well as strong winds in the Guadalupe Mountains.

HIGH PRESSURE WILL BUILD OVER THE AREA EARLY NEXT BRINGING A QUICK WARM-UP WITH HIGHS ABOVE NORMAL.
TONIGHT THROUGH SUNDAY A DYNAMIC UPPER LEVEL LOW WILL CONTINUE TO IMPACT THE REGION AS IT UNDERGOES LEE CYCLOGENESIS TONIGHT AND THEN GETS A MOVE ON OUT INTO THE PLAINS TOMORROW. OUR PORTION OF THIS LOW PRESSURE SYSTEM WILL CONTINUE TO RECEIVE SOME WRAP AROUND MOISTURE BUT WE WILL QUICKLY LOSE THE BETTER DYNAMICS ASSOCIATED WITH THE LOW AND THE JET STREAM BY THIS EVENING. THAT ALLOWED SOME LONG WAVE RADIATION FROM THE HIGH SPRING SUN TO HEAT THE GROUND ENOUGH TO PULL US OUT OF THE SNOW. THIS WILL INCREASE SNOW CHANCES FOR THE LOW ELEVATIONS TONIGHT WHILE SNOW CONTINUES IN THE MOUNTAINS. THE COLDER AIR WILL LEAD TO LOW TEMPERATURES BELOW FREEZING WITH DAMAGE TO SENSITIVE VEGETATION AND LIVESTOCK POSSIBLE IN ADDITION TO FREEZING AND BLACK ICE ON THE ROADS FOR SUNDAY MORNING.
316 PM EDT SAT MAY 9 2015 A LARGE AREA OF HIGH PRESSURE AT THE SURFACE AND ALOFT WILL REMAIN IN CONTROL OF OUR WEATHER THROUGH THE WEEKEND. A BEAUTIFUL SPRING DAY IS PRESENT ACROSS CENTRAL NY AND NORTHEAST PA AS A RIDGE ALOFT IS CURRENTLY OVER THE REGION AND HIGH PRESSURE IS LOCATED AT THE SFC.

THERMAL PROFILES REMAIN BELOW FREEZING DOWN TO THE SURFACE ACROSS NORTHWESTERN COUNTIES. THE TRANSITION IS BETWEEN MOBRIDGE TO JUST EAST OF PHILIP. EXPECT CONVECTION TO WEAKEN NORTH OF THE WARM FRONT.
151 PM EDT SAT MAY 9 2015 A LARGE AREA OF HIGH PRESSURE REMAINS OVER THE WESTERN ATLANTIC THIS WEEKEND. LOW PRESSURE.
EXPECT SHOWERS AND A FEW THUNDERSTORMS AS A COLD FRONT AND ASSOCIATED LOW PRESSURE SYSTEM MOVE OVER THE AREA. AN UPPER LEVEL LOW PRESSURE SYSTEM WILL TRACK EAST NORTHEASTWARD ALONG THE COLORADO AND NEW MEXICO BORDER TODAY BRINGING A CHANCE FOR SHOWERS. A SECONDARY UPPER LEVEL TROUGH WILL CROSS SUNDAY AND SUNDAY NIGHT KEEPING LIGHT PRECIPITATION IN THE FORECAST FOR MANY AREAS.
POWERFULL UPPER LOW OVER SW COLORADO PUSHING COPIOUS MOISTURE NORTHWARD INTO THE HIGH PLAINS. BUT TRACK OF UPPER LOW TO THE NEBRASKA PANHANDLE BY SUNDAY WILL BRING THOSE DYNAMICS A LITTLE CLOSER TO OUR FORECAST AREA. UPPER LOW DRIFTS INTO THE DAKOTAS BY SUNDAY EVENING.
HIGHER PRESSURE OVER THE AREA AND WEAKER ONSHORE FLOW WILL BRING WARMER TEMPERATURES THROUGH SUNDAY.
UPPER LEVEL LOW OVER THE SOUTHWEST USA AND AN ASSOCIATED TROUGH EXTENDING THROUGH MONTANA WILL CONTINUE TO MOVE SLOWLY EAST TODAY. UPPER LEVEL TROUGH OVER MONTANA MOVES SLOWLY EAST AS RIDGING BUILDS ALONG THE WEST COAST WITH NORTHERLY FLOW ALOFT PREVAILING OVER MONTANA THROUGH LATE SUNDAY MORNING. MID LEVEL CLOUD COVER AND LIGHT SHOWERS ASSOCIATED WITH CLOSED UPPER LOW OVER CENTRAL ROCKIES WILL CONTINUE TO AFFECT SOUTHWEST MONTANA THROUGH THE FORECAST PERIOD.
