724 AM EDT THU SEP 17 2015 CURRENT SYNOPTIC PATTERN SHOWS A LARGE UPPER RIDGE ANCHORED OVER TEXAS WITH A WEAK UPPER TROUGH TO ITS EAST AND STRETCHING FROM THE EASTERN GULF AND FLORIDA PENINSULA. A REFLECTION OF THIS UPPER TROUGH WAS NOTED AT THE SURFACE AND SPARKING SCATTERED SHOWERS ACROSS SOUTHEAST GEORGIA THIS MORNING. THE CLOUDS AND EASTERLY FLOW WILL WARRANT LEANING TOWARD THE COOLER SIDE OF GUIDANCE FOR HIGHS EACH DAY. MEDIUM RANGE MODELS CONTINUE TO SHOW MAINLY DRY AND SEASONAL WEATHER THROUGH THE END OF THE WEEK AND MOST OF THE WEEKEND AS THE REGION REMAINS UNDER THE EASTERN END OF A FLAT UPPER RIDGE.
HIGH PRESSURE WILL PROVIDE LIGHT AND VARIABLE WINDS TODAY. WINDS WILL BECOME NORTHERLY AND INCREASE LATE TONIGHT BEHIND A DRY COLD FRONT.
1143 AM EDT MON APR 4 2016 A COLD FRONT WITH LIMITED MOISTURE WILL MOVE THROUGH TONIGHT.
620 AM CDT MON APR 4 2016 COLD FRONT WILL BE WELL SOUTH OF THE AREA TODAY AS HIGH PRESSURE BUILDS OVER THE PLAINS. HIGHS WILL BE MUCH COOLER THAN YESTERDAY IN THE MID 50S TO LOWER 60S. UPPER TROUGH MOVING INTO THE PACIFIC NORTHWEST WILL MAKE PROGRESS INTO THE ROCKIES OVERNIGHT. A LEAD PIECE OF ENERGY TOPPING THE RIDGE ACROSS THE PLAINS COULD HELP TRIGGER SCATTERED SHOWERS ACROSS THE MID MISSOURI VALLEY REGION OVERNIGHT. WHICH SHOULD HELP TO KEEP LOWS IN THE LOWER TO MID 40S. BUT WILL LIKELY SEE ADDITIONAL SHOWERS/STORMS DEVELOP AHEAD OF A COLD FRONT THAT WILL MOVE INTO THE AREA DURING THE AFTERNOON. COULD SEE A MARGINAL RISK OF SEVERE STORMS ALONG/AHEAD OF THE COLD FRONT.
TEMPERATURES AS OF 16Z ARE RUNNING AROUND 10 TO 15 DEGREES ABOVE VALUES YESTERDAY AT THIS TIME WITH MANY SITES ACTUALLY AT THE HIGHS FROM YESTERDAY. THE COLD FRONT THAT IS FORECAST TO MOVE THROUGH THE AREA LATER TODAY IS CURRENTLY LOCATED OVER THE OH RIVER VALLEY AND FORECAST GUIDANCE HAVE IT ARRIVING INTO THE AREA AFTER 00Z THIS EVENING, WHICH IS REASONABLE BASED ON IT'S CURRENT SPEED AND LOCATION.
607 AM CDT MON APR 4 2016 A SFC TROF EXTENDS FROM AN INTENSE SFC CYCLONE SITUATED OVER THE OH/MI BORDER WSW THROUGH CENTRAL MO & THE KS TURNPIKE TO THE TX PANHANDLE EARLY THIS MORNING. WHILE A COLD FRONT POSSESSED A SIMILAR ORIENTATION FROM THE IA/MO BORDER THROUGH SRN NEBRASKA TO ERN CO.
THIS WILL RESULT IN A COOLER FORECAST THAN INLAND. AND HELP TO MODERATE THE WARMING RESULTING FROM A BUILDING UPPER RIDGE OVER THE PLAINS. AM EXPECTING A WARMER DAY THAN YESTERDAY. THE UPPER RIDGE OVER THE PLAINS CONTINUES TO BUILD. AM NOT EXPECTING COOLER AIR TO MOVE OVER THE FA. WITH THE UPPER RIDGE REMAINING IN CONTROL. A BIT WARMER NIGHT TONIGHT IS EXPECTED AS COMPARED TO THE PREVIOUS. WARMER CLOSER TO THE COAST.
732 AM EDT MON APR 4 2016 LOW PRESSURE OVER WESTERN LAKE ERIE WILL MOVE INTO NORTHWESTERN PENNSYLVANIA AROUND DAYBREAK AND TO THE EAST COAST BY EVENING. THE LOW WILL FORCE A COLD FRONT SOUTH ACROSS THE AREA THIS MORNING.
A COLD FRONT EXTENDED FROM A LOW OVER EAST CENTRAL MT SOUTHEAST THROUGH THE SD BLACK HILLS INTO EAST CENTRAL NE. GOOD MODEL AGREEMENT THROUGHOUT THE SHORT TERM WITH THE UPPER RIDGE OVER THE INTERMOUNTAIN WEST PROGRESSING EAST ACROSS THE CWA TODAY AND INTO THE GREAT PLAINS TONIGHT. NEXT POTENT UPPER LOW AND COLD FRONT TO AFFECT THE CWA WILL TRACK EAST ACROSS MT. THE STRONGEST PRESSURE FALLS ASSOCIATED WITH THE PREFRONTAL TROUGH WILL DEVELOP ACROSS NORTHEAST WY/WESTERN SD TUESDAY MORNING WITH STRONG WESTERLY WINDS. DID NOT ISSUE ANY HIGH WIND HIGHLIGHTS AS THERE ARE SOME TIMING DIFFERENCES WRT THE COLD FRONTAL PASSAGE. TEMPERATURES WILL BE 10 TO 15 DEGREES COOLER TUESDAY WITH STRONG AND GUSTY WEST TO NORTHWEST WINDS OF 35 TO 45 MPH.
WINDS WILL SHIFT TO THE NORTH THIS AFTERNOON AS A WEAK COLD FRONT MOVES THROUGH THE REGION. A SHOT OF COOLER AIR WL BRIEFLY RETURN TO THE REGION TNGT AND TUE. HIGHS TUE WL BE ABT 5 TO 10 DEGREES COOLER.
955 AM MDT MON APR 4 2016 UPPER RIDGE MAKING ITS WAY ACROSS COLORADO AT THIS TIME. WITH A TURN TO SWLY FLOW ALOFT ON THE BACK SIDE OF THE PASSING RIDGE AND FRONT SIDE OF THE APPROACHING UPPER TROUGH CURRENTLY OVER NEVADA. OTHER FORECAST COMPONENTS APPEAR ON TRACK WITH HIGHS IN THE LOW TO MID 70S TOGETHER WITH GENERALLY LIGHT S/SWLY WINDS ON THE PLAINS TODAY. AND MAINLY 50S ACRS THE HIGH COUNTRY.
Surface trof has passed over much of the forecast area early this morning, although the well mixed air masses on both sides still bringing lows only down into the 50s north of the boundary so far. As warm advection returns with the low level jet overnight, better focus for showers and storms look to focus more north of the area. By Tuesday morning, a mid-level trough will be over the northern Rockies, with this trough deepening as it advances further east into the Northern and Central Plains through the day. Despite the cloud cover, the strong southerly flow should boost afternoon high temperatures into the low to upper 70s. Showers and thunderstorms should diminish from west to east during the evening and early overnight hours as the cold front progresses eastward out of the area.
WATER VAPOR SATELLITE PICS FROM THIS MORNING SHOWING WELL DEFINED UPPER LOW PUSHING INTO CENTRAL OREGON AS OF 1530Z.

TEMPERATURES ARE TRENDING A LITTLE WARMER THAN PREVIOUSLY FORECAST AND SATELLITE IMAGES ARE SHOWING CLEAR SKIES OVER ALL OF MIDDLE TENNESSEE. WITH AT LEAST A COUPLE OF HOURS BEFORE THE COLD FRONT GETS HERE, WE COULD WARM UP SLIGHTLY MORE THAN PREVIOUSLY THOUGHT. SO I INCREASED THE HIGH TEMPERATURES FOR TODAY ONLY A DEGREE ACROSS THE AREA AND TWEAKED HOURLY TEMPS TO MATCH OBSERVATIONS. THIS WEAK COLD FRONT SHOULD SWING DOWN FROM KENTUCKY AROUND 18Z. COLD FRONT WILL MOVE ACROSS AIRPORTS TODAY WITH FEW/SCT LOW CLOUDS.
/issued 324 AM CDT MON APR 4 2016/ Dry NW flow aloft and prominent low level thermal ridging will lead to unseasonably warm wx Mon/Tue with high temperatures around 10 degrees above normal. A mid level trof passing to the n early Wed AM will push a fast moving front (isallobaric high of 7mb/3hr) swd thru the CWFA result in windy conditions around 12Z-18Z. High temperatures Wed will be about 10-15 degrees cooler than Tue. Gusty se upslope winds Fri along with thickness cooling/clouds will keep temperatures cooler, even slightly below normal. Even though we are not issuing a watch for the plains we acknowledge the fire danger will be very to high to extreme and that there will be a prominent low level thermal ridge across SE NM/W PB.
THE SYSTEM'S COLD FRONT HAS ALREADY MOVED INTO EXTREME NORTHEAST WASHINGTON AND IDAHO. ISOLATED TO SCATTERED SHOWERS WILL PERSIST INTO THE AFTERNOON AS THE UPPER TROUGH AXIS MOVES THROUGH THE AREA. WINDS ARE BEGINNING TO INCREASE IN THE KITTITAS AND YAKIMA VALLEYS, AS WELL AS IN THE LOWER BASIN. THESE AREAS AND AS WELL AS THE LOWER BASIN IN OREGON AND WASHINGTON, AND THE WASHINGTON BLUE MOUNTAIN FOOTHILLS COULD SEE GUSTS TO AROUND 50 MPH DUE TO MIXING DOWN OF HIGHER LEVEL WIND THIS AFTERNOON. THUS HAVE ADDED THE LOWER BASIN ZONES AND THE WASHINGTON FOOTHILL ZONE TO THE CURRENT GROUP OF ADVISORIES.
