STUBBORN HIGH PRESSURE RIDGE IN THE MID/UPPER LEVELS OVER THE FLORIDA PENINSULA WILL KEEP UNSEASONABLY WARM TEMPS ACROSS THE REGION AS TROF TRIES TO DIG INTO THE SOUTHEASTERN U. MORNING SOUNDING SHOWS A LARGE CAP AROUND 700 MB AND VERY WARM TEMPS IN THE MID LEVELS AT 500 MB SO IT WILL BE TOUGH TO GENERATE THUNDERSTORM ACTIVITY CLOSER TO THE RIDGE. BUT A FEW ISOLD STORMS ACROSS INLD SE GA WILL BE POSSIBLE AS THE TROF EDGES CLOSER LATER TODAY. WHILE THE COASTAL AREAS AND ACROSS SE GA WILL REMAIN IN THE LOWER/MIDDLE 80S.

WINDS SHOULD ALSO RESPOND TO THE NORTHEAST AS THE LOW BEGINS TO MOVE THAT WAY. WINDS SHOULD BE WEAKER ON THE BACK SIDE OF THIS LOW AS IT PASSES AND FLAGS SHOULD BE ABLE TO LOWER BY TONIGHT.
THE COLD FRONT IS SLOWLY MOVING THROUGH SOUTHERN OREGON OVERNIGHT. THE FORECAST AREA WILL REMAIN UNDER NORTHWEST FLOW ALOFT WITH A FEW SHORT WAVE TROUGHS AND MID LEVEL MOISTURE. A COLD FRONT HAS REACHED THE UMPQUA DIVIDE AND WILL CONTINUE SOUTHEAST ACROSS THE ROGUE VALLEY THEN SOUTH CENTRAL OREGON AND NORTHERN CALIFORNIA OVERNIGHT INTO SUNDAY MORNING. THIS WILL RESULT IN A MIX OF MVFR AND VFR CEILINGS WITH LIGHT TO MODERATE RAIN BUT ALSO WIDESPREAD OBSCURATION OF THE HIGHER TERRAIN.
WHEREAS WINDS ON THE MTN PEAKS AND HIGHER RIDGES ALONG THE CONTINENTAL DIVIDE AND ON HIGHER TERRAIN ALONG THE WYOMING BORDER ARE MORE THAN LIKELY REMAIN NEARLY AS STRONG THROUGHOUT THE DAY DUE TO THE 90-120KT QUASI- ZONAL FLOW ABOVE 500 MBS. AS HEIGHTS RISE WITH THE PASSING UPPER RIDGE TODAY. NOTHING TERRIBLY THICK DUE TO THE LOW AMPLITUDE OF THE MTN WAVE DURING THE DAYLIGHT HOURS. TEMPERATURES TODAY WILL REMAIN WELL ABOVE AVERAGE WITH 70S BY AFTERNOON ON THE PLAINS AND BALMY UPPER 40S/50S ACROSS THE HIGH COUNTRY. GUSTS IN THE 50-65 MPH A GOOD BET IN THE FOOTHILLS AND ON MTN RIDGES.

AN UPPER LEVEL TROUGH OF LOW PRES MOVING ACROSS THE PACIFIC NW OVER THE NEXT FEW DAYS WILL BRING COOL SHOWERY WEATHER TO THE REGION. AROUND MIDWEEK EXPECT A SHORT BREAK FROM THE SHOWERS AS A RIDGE OF HIGH PRES NUDGES IN. MAIN UPPER TROUGH BEGINS TO SHIFT E OF THE FORECAST AREA MON NIGHT AND TUE.
MORNING UA ANALYSIS INDICATES CLOSED UPPER LOW OVER SRN TX WHILE 593DM RIDGE OVER SRN FL. EXPECT THIS UPPER RIDGE TO SLOWLY FLATTEN OUT AND SLOWLY BUILD E TODAY WHILE THE UPPER LOW BECOMES MORE OPEN S/WV AND PROPAGATES FAIRLY QUICKLY TO THE NE TODAY. NOT EXPECTING REALLY ANY SEVERE POTENTIAL TODAY AS THE ONLY AREA POSSIBLE IN THE SE THE LOW LEVEL JET IS MUCH WEAKER.

A COLD FRONT IS PROGGED TO PUSH INTO NORTH GEORGIA LATE TONIGHT.
DRY WEATHER WILL CONTINUE TONIGHT AND EARLY WEDNESDAY AS RIDGING MOVES OVER THE PACIFIC NORTHWEST. CHANCES FOR RAIN WILL INCREASE WEDNESDAY AFTERNOON AS A STORM OVER THE ALEUTIAN ISLANDS SHIFTS TO THE SOUTHEAST AGAINST THE UPPER RIDGE POSITIONED OVER THE WESTERN UNITED STATES.
A HIGH PRESSURE SYSTEM WAS CENTERED OVER WISCONSIN THIS AFTERNOON BUT THERE WAS STILL QUITE A BIT OF CLOUD COVER ACROSS THE FORECAST AREA AT 20Z. RHINELANDER TIME/HEIGHT PLOT ON BUFKIT FROM THE 12Z NAM SHOWED SHALLOW MOISTURE WITH SUBFREEZING SURFACE TEMPERATURES. 01 INCH OF FREEZING PRECIPITATION THERE BETWEEN ABOUT 06Z AND 10Z. 01 FREEZING PRECIPITATION IN NORTHERN WISCONSIN. AS WARMER AIR AND DEEPER MOISTURE ADVECT INTO NORTHERN WISCONSIN ANY FREEZING PRECIPITATION SHOULD CHANGE TO RAIN. WITH THE HIGHEST TOTALS LIKELY TO BE ACROSS THE NORTH.
341 AM CST WED DEC 16 2015 DRY SLOT ROTATING AROUND THE AREA OF LOW PRESSURE OFF TO THE NORTHWEST PUSHING THROUGH THE CWA CURRENTLY.
Currently, 20z hour WV and Visible satellite imagery shows a mid- upper level low swirling over northwest KS, southwest NE and northeast CO vicinity. Have lowered temps into the upper 20s over east central KS and lower 30s over the rest of northeastern KS due to a west/northwest wind developing as the low pressure system previously mentioned lifts to the northeast through eastern Nebraska dragging a cold front through as well. Cold air advection behind it should bring a slightly cooler day as 850mb temps fall to around -8C.
LATEST INDICATIONS ARE THAT THE H7-H5 THETA-E RIDGE AXIS/TROWAL FEATURE WILL BEGIN TO SHIFT EAST OF BISMARCK INTO THE JAMES RIVER VALLEY BETWEEN 15Z-18Z WEDNESDAY. SNOW TOTALS IN BISMARCK COULD VERY WELL BE ON THE HIGH END OF THE ADVERTISED 4 TO 6 INCH RANGE FOR THE CITY.
