A SHORT WAVE ROTATING AROUND THE LOW WILL MOVE ONSHORE OVER NORTHERN CALIFORNIA THIS EVENING. THE TROUGH WILL REMAIN OVERHEAD MONDAY WITH WEAKER SHORT WAVES MOVING THROUGH. IT WILL BE MUCH COOLER WITH INLAND HIGHS 15-25 DEGREES COOLER THAN THE SUNDAY HIGHS.
1257 PM EDT SUN MAY 31 2015 ATLANTIC HIGH PRESSURE WILL PREVAIL THROUGH MONDAY.
A much quieter stretch of weather appears to finally be on tap for the region for the coming week, as ridging both at the surface and aloft look to remain in place over the area for the next few days. This will persist through at least mid morning, with fog and drizzle most prevalent along the spine of the Ozark Plateau, where stratus is more prone to build down toward the higher elevations. The slow clearing trend will continue Monday, though right now things are looking more cloudy than not as an upper low remains parked over southeastern Arkansas.
448 AM EST MON FEB 1 2016 HIGH PRESSURE WILL MOVE ACROSS THE AREA TODAY AND TONIGHT PROVIDING FAIR WEATHER. HIGHS TODAY WILL GENERALLY BE IN THE LOWER TO MIDDLE 40S WITH LOWS TONIGHT IN THE UPPER 20S AND LOWER 30S.

THE UPPER LOW THAT BROUGHT ALL OF TODAYS WEATHER IS NOW TO THE EAST OF THE AREA AND IS MOVING TOWARDS THE NV BORDER. UNSTABLE AIR SWEEPING AROUND THE BACKSIDE OF THE LOW IS BRINGING QUITE A BIT OF SHOWER ACTIVITY TO THE OUTER WATERS.
A WARM FRONT WILL TRACK NORTHEAST ACROSS THE PANHANDLES MONDAY CAUSING THE SOUTHEAST WINDS TO SHIFT TO THE SOUTH AND SOUTHWEST AROUND 15Z TO 18Z MONDAY AND WINDS WILL INCREASE TO AROUND 20 TO 30 KNOTS WITH GUSTS NEAR 40 TO 45 KNOTS.
OTHERWISE THE LOW CLOUDS CURRENTLY EXTEND FROM NEAR KDVL DOWN THRU HILLSBORO AND TO NEAR KAXN.
1132 PM CST SUN JAN 31 2016 A COLD FRONT IS PUSHING SE THROUGH THE STATE LATE THIS EVENING. THIS FRONT WILL LIFT BACK NORTH AS A WARM FRONT MON AFTERNOON AND EVENING. /ISSUED 507 PM CST SUN JAN 31 2016/ COLD FRONT IS CURRENTLY MOVING SE THROUGH THE STATE.

TONIGHT THROUGH MONDAY NIGHT LATEST SURFACE ANALYSIS INDICATES THE COLD FRONT HAS REACHED A LINE FROM HARRISON. THE ASSOCIATED COLD FRONT WILL APPROACH THE STATE LATE IN THE PERIOD.
1250 AM EST MON FEB 1 2016 A COLD FRONT WILL MOVE THROUGH TONIGHT. HIGH PRESSURE WILL BRIEFLY WORK INTO THE REGION FOR MONDAY.
318 AM CST MON FEB 1 2016 COOLER CONDITIONS ARE CURRENTLY BEING FELT COMPARED TO THIS TIME YESTERDAY DUE TO THE PASSAGE OF A WEAK COLD FRONT. IN FACT IT LOOKS LIKE THE BOUNDARY HAS ALREADY BEGUN TO LIFT NORTH IN RESPONSE TO LEE ROCKIES CYCLOGENESIS ASSOCIATED WITH AN UPPER LEVEL LOW PRESSURE SYSTEM OVER THE SOUTHWEST STATES. THE UPPER LOW CAN BE SEEN MARCHING EASTWARD ON SATELLITE AND IS PRODUCING CONVECTION OVER ARIZONA AND NEW MEXICO.
EXPECT MORE PATCHY FOG AND SOME LOW CIGS TO DEVELOP OVERNIGHT ACROSS THE REGION AS A COLD FRONT CURRENTLY OVER SW AR/NE TX AND EXTREME NW LA WILL STALL TONIGHT AND LIFT BACK NWD AS A WARM FRONT. /ISSUED 954 PM CST SUN JAN 31 2016/ COLD FRONT MOVING INTO SOUTHWEST ARKANSAS.

1140 PM CST SUN JAN 31 2016 RELATIVELY QUIET WEATHER EXPECTED FOR THE NEXT 24 HOUR WITH A VERY WEAK TROUGH AXIS/COLD FRONT DRAPED ACROSS THE AREA. AND I EXPECT IT TO INCREASE CLOUD COVER AND BRING SOME VERY SMALL CHANCES FOR LIGHT SNOW NEAR THE TROUGH AXIS.
ANOTHER BAND OF SHOWERS WAS LOCATED FURTHER TO THE NORTHWEST, NEAR THE OHIO RIVER VALLEY, ALONG A COLD FRONT. STILL LOOKS LIKE THE COLD FRONT WILL BE NEAR OUR NORTHWESTERN COUNTIES BY 06Z, AND IN THE NASHVILLE AREA BY 09Z, AND PUSH INTO SOUTHERN AND EASTER AREAS LATE TONIGHT AND EARLY MONDAY MORNING. HAVE UPDATED FORECAST GRIDS TO MORE CLOSELY REFLECT LATEST TRENDS AND FORECAST MOVEMENT OF COLD FRONT ACROSS THE AREA TONIGHT.
1136 PM EST SUN JAN 31 2016 AVIATION LOW PRESSURE WILL MOVE EAST OF LOWER MICHIGAN THIS EVENING WITH PRECIPITATION ENDING FROM WEST TO EAST.
Low level moisture will continue to increase today as southerly return flow continues ahead of the next large upper level trough currently digging into the southwest states. A warm air mass is in place with daytime high temperatures expected to be well above average, ranging from the low to mid 70s across the western portions of the area to the mid to upper 70s across the eastern portions.

1152 PM CST SUN JAN 31 2016 Updated aviation discussion for 06Z TAF issuance The cold front is making good progress across the region, especially through the Evansville Tri State.
A COLD FRONT CURRENTLY STRETCHES SOUTHWESTWARD FROM CINCINNATI TO BOWLING GREEN TO JUST EAST OF MEMPHIS. THE COLD FRONT AND PRECIPITATION WILL MAKE SLOW PROGRESS ACROSS THE AREA AS THE UPPER LEVEL TROUGH RACES OFF QUICKLY TO THE NORTHEAST. DRIER AIR MOVES INTO THE MID AND UPPER LEVELS AS SOME OF THE MODELS ARE SHOWING WEAK RIDGING ALOFT. THE LOWER LEVELS REMAIN SATURATED WITH LIGHT RAIN/DRIZZLE EXPECTED TO CONTINUE THROUGHOUT THE NIGHT.
315 AM EST MON FEB 1 2016 LATEST SURFACE ANALYSIS SHOWS VESTIGES OF HIGH PRESSURE HANGING ON OVER SOUTHEAST PORTIONS OF GEORGIA WHILE THE NORTHERN PORTION IS SLOWLY TRANSITIONING AS A WEAK FRONT MOVES THROUGH THE TENNESSEE VALLEY. CLOUDS WILL ATTEMPT TO TEMPS IN CHECK THIS AFTERNOON BUT BETTER CHANCES OF CLEARING TO THE SOUTH WILL RESULT IN TEMPS APPROACHING THE LOW TO MID 70S.
107 AM EST MON FEB 1 2016 LOW PRESSURE WILL TRACK FROM THE GREAT LAKES TO QUEBEC TONIGHT INTO MONDAY. GRADUALLY PUSHING A WEAK COLD FRONT THROUGH THE MID ATLANTIC STATES MONDAY NIGHT.

SCATTERED -SHRA ARE EXPECTED TO DEVELOP AND INCREASE, ESPECIALLY AFTER 10Z AS A COLD FRONT APPROACHES FROM THE NW.
low pressure over western north TX along the retreating frontal boundary and over the TX panhandle in association with the main system will merge/consolidate near the OK/KS border tonight.
1140 PM CST SUN JAN 31 2016 A weak cold front was in the process of moving through the Ozarks this afternoon. Winds will turn out of the south again Monday morning as low pressure moves into the plains. A storm system will move towards the region through the day Monday with a warm front lifting across the area.
TEMPS ARE IN THE LOWER/MID 60S SOUTH OF THE BOUNDARY SO IT WON'T TAKE MUCH HEATING TO BUMP TEMPS INTO THE UPPER 70S THIS AFTERNOON. AN AREA OF LOW PRESSURE OVER SE COLORADO WILL STRENGTHEN TONIGHT AND TIGHTEN THE GRADIENT SO WINDS SHOULD BEGIN TO INCREASE THIS AFTERNOON INTO TONIGHT. AS THE LOW PUSHES TO THE NE. A WEAK PRE FRONTAL TROUGH OR WHAT LOOKS LIKE A DRY LINE SHOULD CROSS THE AREA.
A STRONG UPPER LEVEL LOW PRESSURE SYSTEM WILL CROSS NORTHERN NEW MEXICO LATE TONIGHT THROUGH MONDAY NIGHT WITH A FEW TO SEVERAL INCHES OF SNOW ACROSS NORTHERN AND WESTERN AREAS.
240 AM MST MON FEB 1 2016 THE COLD UPPER LOW WILL TRACK ALONG THE CO-NM BORDER TODAY BRINGING WIDESPREAD UPPER DYNAMICS AND COLD ADVECTION TO THE ENTIRE FORECAST AREA. THE BEST FRONTOGENETICAL FORCING WITH THIS FEATURE NOW SEEMS TO FAVOR THE WESTERN SAN JUANS AND THE PICEANCE BASIN INTO THE LOWER YAMPA RIVER BASIN BASICALLY MISSING THE I-70 CORRIDOR.
HIGH PRESSURE IS BUILDING IN BEHIND THE SEASONALLY WEAK COLD FROPA EARLIER TODAY.
scattered mid/high clouds look to develop with winds continuing to shift out of the east- southeast and become breezy ahead of the next approaching low pressure system. Cold front has pushed east of the forecast area with winds briefly subsiding across the area overnight.
232 AM CST MON FEB 1 2016 COLD FRONT JUST ENTERING NORTHWEST MIDDLE TENNESSEE AT THIS TIME WITH SHOWERS ALONG FRONTAL BOUNDARY.
1040 PM CST SUN JAN 31 2016 UPDATED AVIATION PORTION FOR 06Z TAF ISSUANCE SENT OUT AN UPDATE TO THE FORECAST FOR CLEARING SKIES AND A SPECIAL WEATHER STATEMENT FOR EASTERN COUNTIES FOR SLIPPERY ROADS AS SKIES CLEAR AND TEMPERATURES FALL QUICKLY FREEZING PAVEMENT WET FROM RAIN AND MELTED SNOW.
SHORT TERM: (Through Late This Afternoon) Cooler temperatures today than the past few days as high pressure moves from the northern Plains across the Midwest. Wind will swing around from the north to the east as the ridge axis shifts over the Ohio Valley and low pressure moves out of the Four Corners region into far southeast Colorado. Guidance is in good agreement with temperatures ranging from the upper 40s in northeast Missouri to the low and mid 50s along and south of the I-70 corridor. System still looks much warmer than it did a few days ago, and I don't think there's any chance left for wintry precipitation in our CWFA with the initial round.
ASCENT NEAR AND N OF THE WARM FRONT WILL ALLOW FOR AN INCREASING COVERAGE OF SHRA ACROSS SRN TERMINALS BTWN 09-11Z. IT APPEARS THAT SLOW NWD ADVANCEMENT OF WARM FRONT DURING THE DAY WILL LIMIT THREAT FOR SHRA/TSRA AT PBI WITH MOST ACTIVITY FOCUSED AT THE MIAMI-DADE/BROWARD TERMINALS. WITH THE HIGHEST MOISTURE RIDING OVER SOUTHEAST FLORIDA. BUT SPEEDS IN THE LOW LEVEL ARE NOT SO IMPRESSIVE. A TROUGH DIGGING INTO THE WESTERN U. ALLOWING A RIDGE TO PUMP UP ACROSS THE SOUTHEAST. THE NEXT COLD FRONT IS FORECAST TO MOVE INTO NORTH FL ON WED THEN INTO CENTRAL FL BY THU.

1049 AM EDT THU OCT 15 2015 SHOWERS WILL ACCOMPANY A COLD FRONT ACROSS THE UPPER OHIO VALLEY REGION TONIGHT.
THE MAIN FORECAST CONCERN REMAINS THE ARRIVAL OF A COLD FRONT THIS AFTERNOON/EVENING AND THE CHANCE FOR SHOWERS AND THUNDERSTORMS ACROSS SOUTH CENTRAL AND SOUTHEAST KANSAS. WITH THE COMBINATION OF 850 MB WARM AIR ADVECTION AHEAD OF THE COLD FRONT AND COOLING TEMPERATURES ALOFT ALONG THE FRONT. AFTER THE COLD FRONT PASSES. HIGH PRESSURE WILL DROP INTO THE REGION BEHIND THE COLD FRONT USHER IN COLD AND DRY CANADIAN AIR.
HIGH PRESSURE ALOFT WILL PREVAIL OVER THE REGION THROUGH TONIGHT AND THEN MOVE SLOWLY EAST ON FRIDAY.
The greatest chances for near Red Flag looks to be over Southeast Oklahoma where a few gusts up around 20 mph and the lowest RH values should be co-located. Mostly sunny skies along with the above seasonal average temperatures will aid in near record high temps this afternoon ahead of the developing cold front to the north.
THE COLD FRONT IS STARTING TO ENTER THE PANHANDLE LATE THIS MORNING. CAA WILL INCREASE ACROSS THE PLAINS AS THE UPPER TROUGH DIGS SOUTH OVER THE GREAT LAKES AND NORTHERN MIDWEST. SFC CONVERGENCE WILL INCREASE ALONG THE COLD FRONT AS IT MAKES ITS WAY INTO WESTERN OK WHERE A COUPLE OF STORMS MAY TRY TO DEVELOP BEFORE 00Z WITHIN INSTABILITY AXIS. /ISSUED 539 AM CDT THU OCT 15 2015/ SOUTH TO SOUTHWEST WINDS WILL PREVAIL AHEAD OF A COLD FRONT TODAY WITH VFR CONDITIONS.
