TEMPERATURES WILL BE A LITTLE BELOW AVERAGE, THEN WARMER BY THE WEEKEND. DEEP CLOSED UPPER LOW REMAINS NEARLY STATIONARY AROUND 40N/130W. CLOUDS ASSOCIATED WITH THE LOW ARE MOSTLY OFFSHORE OR ALONG THE COAST, SO SKIES ACROSS THE REGION ARE CLEAR EARLY THIS MORNING. INTERIOR NORCAL REMAINS TOO FAR TO THE EAST OF THE LOW TO SEE MUCH IMPACT OTHER THAN TEMPERATURES REMAINING AROUND OR SLIGHTLY BELOW AVERAGE FOR MID-AUGUST.
319 AM CDT WED AUG 12 2015 THE SURFACE COLD FRONT HAS MOVED WELL SOUTH OF THE AREA AND IS NOW LOCATED ALONG THE INTERSTATE 85 CORRIDOR. WITH TEMPERATURES EXPECTED TO BOTTOM OUT IN THE LOWER 60S ACROSS THE EAST. WITH HIGH PRESSURE SETTLING IN ACROSS THE REGION.
253 AM EDT WED AUG 12 2015 COOLER AND DRIER AIR WILL MOVE INTO THE REGION IN THE WAKE OF A COLD FRONT MOVING OFF THE EASTERN SEABOARD. TEMPERATURES WILL REBOUND LATER THIS WEEK WITH HIGH PRESSURE BUILDING EAST FROM THE MID MISSISSIPPI VALLEY. AS CYCLONIC UPPER FLOW AND DEEPENING COLD AIR ALOFT WILL SUPPORT THE CONTINUED MENTION OF CLOUDS AND ISOLATED SHOWERS HANGING IN OVER THE HIGHER TERRAIN OF THE NORTH OVERNIGHT. THE UPPER TROUGH AND COLD POOL WILL BOTTOM OUT OVER THE AREA WEDNESDAY.
ON THE LARGE SCALE, HIGH PRESSURE OVER TEXAS AND TROUGH OVER THE EASTERN THIRD OF THE UNITED STATES WILL RETROGRADE (SHIFT WEST) SLIGHTLY OVER THE NEXT FEW DAYS. TROUGH INTO NORTH FLORIDA AND THE EASTERN GULF OF MEXICO. LOCALLY, THE LOW/MID LEVEL RIDGE AXIS IS EXPECTED TO REMAIN NEARLY STATIONARY OVER THE STRAITS OF FLORIDA AND EXTREME SOUTHERN TIP PENINSULA, KEEPING A SW/W LOW/MID LEVEL FLOW ACROSS OUR REGION. THE GULF COAST (INCLUDING NAPLES AND MARCO ISLAND AREAS) WILL HAVE THE LOWEST POPS/COVERAGE UNDER THIS FLOW REGIME WITH ANY PRECIP OCCURRING IN THE MORNING TO EARLY AFTERNOON TIME FRAME. AS IS TYPICAL, A FEW STORMS COULD CONTAIN GUSTY WINDS, WITH THURSDAY BEING THE DAY MOST LIKELY TO SEE STRONGER STORMS/WIND GUSTS DUE TO SLIGHTLY COOLER AIR ALOFT FROM THE DEEPENING EASTERN U. TROUGH.
311 AM EDT WED AUG 12 2015 A COLD FRONT WILL MOVE ACROSS THE AREA THIS MORNING.
NEAR TERM AND SHORT TERM SECTIONS HAVE BEEN UPDATED BELOW BENIGN WEATHER PATTERN CONTINUES WITH HIGH PRESSURE IN PLACE ALOFT AND AT THE SURFACE FOR MOST OF THE SHORT TERM PERIOD.

158 AM EDT WED AUG 12 2015 SCATTERED SHOWERS WILL LINGER INTO WEDNESDAY AS AN UPPER TROUGH MOVES ACROSS THE AREA. FAIR WEATHER IS FORECAST FOR THURSDAY WHEN HIGH PRESSURE BUILDS INTO THE REGION.
NWP MODELS HAVE GOOD CONSENSUS WITH TROUGH CONTINUING TO ESTABLISH ITSELF ACROSS THE EASTERN CONUS. WHILE A UPPER LEVEL HIGH RETROGRADES WEST INTO THE FOUR CORNERS REGION. WHILE THIS TROUGH IS NOT SUPER ABNORMAL WITH A STANDARD DEVIATION OF -1. THIS IS OF COURSE AIDED BY A CANADIAN HIGH PRESSURE THAT WILL SETTLE ACROSS THE REGION BY THURSDAY MORNING. UPPER LEVEL TROUGH ALONG THE EAST COAST TO START THE PERIOD WILL SPLIT LEAVING THE TAIL END TO SLOWLY RETROGRADE ACROSS THE SOUTHERN APPALACHIANS TO SOUTH TEXAS BY THE END OF THE PERIOD.
613 AM EDT WED AUG 12 2015 A COLD FRONT WILL MOVE ACROSS THE AREA THIS MORNING.

856 PM CST SAT FEB 20 2016 A HIGH PRESSURE RIDGE EXTENDED ACROSS FL TO THE UPPER AND MID TX COAST THIS EVENING. WHILE A COLD FRONT WAS LOCATED OVER FAR N TX. SFC ANALYSIS AT 23Z HAS WE TROUGH OF LOW PRESSURE FROM NE OK THROUGH W TX.
LOW-LEVEL HIGH PRESSURE RIDGE OVER THE ECFL PENINSULA. SO EXPECT PSUNNY SKIES WITH SLGTLY WARMER/MORE HUMID CONDS. HIGH PRESSURE OVER THE AREA WITH A RELATIVELY WEAK PRESSURE GRADIENT.
632 PM EST SAT FEB 20 2016 HIGH PRESSURE OFF THE SOUTHEAST COAST WILL BE SUPPRESSED FARTHER SOUTHWARD AHEAD OF AN APPROACHING COLD FRONT.
909 PM EST SAT FEB 20 2016 GRADUALLY COOLER THROUGH SUNDAY WITH RAIN ARRIVING MAINLY SOUTH OF PITTSBURGH SUNDAY MORNING AS LOW PRESSURE CROSSES THE MID ATLANTIC STATES. HIGH CLOUDS WILL INCREASE OVERNIGHT AS A WAVE OF LOW PRESSURE MOVES ACROSS THE NEARLY STATIONARY FRONT JUST SOUTH OF THE FORECAST AREA. OVERNIGHT LOWS SHOULD BE ABOUT 5 TO 10 DEGREES COOLER THAN LAST NIGHT. WHICH MAY ALLOW FOR AN UPSLOPE SNOW SHOWER OR TWO INTO THE RIDGES OVERNIGHT SUNDAY NIGHT.
522 PM CST SAT FEB 20 2016 228 PM CST CLOUDS WILL BE ON THE INCREASE TONIGHT AS A COLD FRONT DROPS SOUTHWARD ACROSS THE AREA. AND COOLER CONDITIONS.
WITH THESE CIGS EVEN SLOWER TO LIFT SUNDAY AS A COLD FRONT DRIFTS SE INTO EXTREME NE TX/SE OK/WRN AR THROUGH 18Z.
A WEAK COLD FRONT WILL MOVE THROUGH THE AREA SUNDAY EVENING. HIGH PRESSURE WILL REMAIN OVER THE REGION FOR THE START OF THE WEEK. CURRENT LOW TEMPERATURE FORECAST IN THE LOWER 30S SEEMS REASONABLE. HIGH PRESSURE WILL BUILD OVER THE REGION FOR THE START OF THE WEEK.
WINDS WILL GRADUALLY BECOME MORE NORTHERLY OVERNIGHT AND PICKUP AGAIN TOMORROW AS THE PRESSURE GRADIENT TIGHTENS AS LEE SIDE TROUGHING SHIFTS EASTWARD. TEMPS TOMORROW SHOULD BE ON THE ORDER OF 10 DEGREES COOLER THAN TODAY.
NEXT WAVE BEGINS MOVING INTO NW GA SUN MORNING AND PUSHES INTO THE WEAK RIDGE CENTERED OVER SOUTH GA/N FL. THIS IS SAID WITH CAUTION HOWEVER AS THE LAST POTENTIAL SEVERE SCENARIO SEVERAL WEEKS AGO HAD A SIMILAR SETUP THIS FAR OUT BUT THE LOW ENDED UP NEAR CANADA BY THE TIME ALL WAS SAID AND DONE.
A LOW PRESSURE SYSTEM IS APPROACHING THE AREA AND TOWARDS SUNRISE. CHATTANOOGA AIRPORT, TN 54 66 48 61 / 30 80 50 30 KNOXVILLE MCGHEE TYSON AIRPORT, TN 51 63 47 57 / 30 80 60 10 OAK RIDGE, TN 54 63 46 58 / 40 90 50 10 TRI CITIES AIRPORT, TN 49 60 42 53 / 30 80 60 10.
LIGHT WINDS WILL PREVAIL OVERNIGHT BECOMING SOUTHWEST 5-10 KNOTS ON SUNDAY AS RIDGE AXIS PUSHES SOUTHWARD.
SFC ANALYSIS AT 23Z HAS WE TROUGH OF LOW PRESSURE FROM NE OK THROUGH W TX.
The only change was to increase the clouds mainly across southwest Georgia and southeast Alabama given the high clouds that are in place and that are expected to remain for the remainder of the night. High pressure to the east of the region will keep light southerly flow in place across the region tonight. Expect a warmer night with lows generally in the upper 40s to lower 50s.
AND WITH RIDGE BUILDING FROM THE WEST WE SHOULD SEE DRY CONDITIONS PERSIST THROUGH THE REMAINDER OF THE NIGHT. ONLY POTENTIAL HAZARD WOULD BE ANY LOCALIZED SLICK SPOTS FOLLOWING THE EASTERN SNOW SHOWERS AS TEMPS FALL BELOW FREEZING TONIGHT. WEAK UPPER RIDGING WILL MOVE INTO THE AREA ON SUN UNDER A DRIER AIRMASS. MORE VORTICITY AND A PACIFIC COLD FRONT WILL PUSH INTO THE REGION SUN NIGHT BRINGING A CHANCE OF SNOW SHOWERS TO AREAS OVER AND NEAR THE WESTERN MOUNTAINS. AND THE COLD FRONT CROSSES THE AREA. AS AN UPPER LEVEL RIDGE REMAINS STALLED OVER THE PACIFIC COAST. THIS SHOULD RESULT IN TEMPS A BIT COOLER THAN IN RECENT DAYS. EVEN IN THE HIGH TERRAIN.
628 PM EST SAT FEB 20 2016 GRADUALLY COOLER THROUGH SUNDAY WITH RAIN ARRIVING MAINLY SOUTH OF PITTSBURGH SUNDAY MORNING AS LOW PRESSURE CROSSES THE MID ATLANTIC STATES.

AND HIGHEST POPS FROM MORGANTOWN TO THE SOUTHEAST RIDGES. WHICH MAY ALLOW FOR AN UPSLOPE SNOW SHOWER OR TWO INTO THE RIDGES OVERNIGHT SUNDAY NIGHT.
UPPER LEVEL RIDGE WILL REMAIN OVER THE AREA THROUGH SUNDAY. TEMPERATURES WILL AVERAGE 3 TO 6 DEGREES WARMER ON SUNDAY.
COLD FRONT WILL CONTINUE TO MOVE SOUTH DURING THE DAY SUNDAY LIKELY REACHING THE KDRT AROUND 21Z THEN INTO KAUS AROUND 22Z THEN INTO THE SAN ANTONIO TERMINALS ABOUT 23Z. COLD FRONT THAT IS CURRENTLY HELD UP IN THE PANHANDLE WILL START TO MOVE SOUTH OVERNIGHT AND SLOWLY PUSH INTO THE HILL COUNTRY BY LATE SUNDAY AFTERNOON AND INTO THE I-35 CORRIDOR MAYBE BY 00-03Z. BUT SHOWERS AND ISOLATED THUNDER IS POSSIBLE SUNDAY AFTERNOON AND SUNDAY NIGHT AS AN UPPER LEVEL TROF INTERACTS WITH THE SLOW MOVING FRONT.

WHILE A LARGE TROUGH DIGS ACROSS THE WESTERN UNITED STATES. THE SHORT TERM MODELS STILL FOCUS THE HIGHER PRECIPITATION CHANCES IN THE WEST.
638 PM EST MON NOV 2 2015 HIGH PRESSURE OVER THE OHIO VALLEY WILL MOVE SLOWLY TO THE EAST COAST AND A WARM SOUTH TO SOUTHWEST FLOW WILL CONTINUE MUCH OF THE WEEK.
543 PM CST MON NOV 2 2015 High pressure ridge sliding off to the southeast this afternoon, but flow across the state is mainly out of the south/southwest. With the persistence of the higher dewpoints, the development of fog tonight is quicker, and the stratus is further north and lower.
MODELS ARE CONTINUING TO SHOW A MORE WESTERLY SOLUTION WITH THE INCOMING TROUGH. AHEAD OF THE TROUGH. IN THE HIGHER TERRAIN. ASSOCIATED WITH THE MAIN TROUGH PUSHING THROUGH. TEMPERATURES WILL BE A BIT COOLER ALLOWING MUCH OF THE WESTERN ZONES TO SEE SOME ACCUMULATING SNOWFALL.
717 PM EST MON NOV 2 2015 THEN SLIDE EAST LATER IN THE WEEK AS A COLD FRONT SLOWLY APPROACHES FROM THE WEST.
A cold front extended south of this low through the Apalachicola River and well south into the Gulf of Mexico. Even behind the "cold" front, the airmass was warmer than average. A weakening short wave trough was lifting northeastward over GA, with dry, sinking motion near and west of its axis. The latest NWP guidance shows a continued weakening trend in local Q-G forcing overnight as this upper trough and associated frontal wave exit our region to the northeast. However, judging from recent radar trends and high-resolution NWP guidance, there will be enough mesoscale forcing for narrow bands of rain along and ahead of the slow-moving "cold front" overnight.
RIDGING INFLUENCES SFC/ALOFT WILL BECOME THE PREDOMINATE WX FEATURE THRU 03/24Z.
559 PM CST MON NOV 2 2015 WESTERN HIGH PLAINS LOW PRESSURE WILL CONTINUE TO ORGANIZE TONIGHT AS ENERGY CROSSES THE ROCKIES.

MUCH OF THIS STRATUS HAS DISSIPATED WITH DAYTIME HEATING HOWEVER THE LOW LEVEL MOISTURE REMAINS. THIS WILL ALLOW THE LOW LEVEL MOISTURE TO STREAM NORTH OVERNIGHT AND SHOULD REACH SOUTHERN IOWA BY 12Z TUESDAY. LOCALIZED FOG WILL BE POSSIBLE AS THE LOW LEVEL MOISTURE ARRIVES.
627 PM EST MON NOV 2 2015 HIGH PRESSURE WILL REMAIN IN CONTROL ACROSS THE REGION THROUGH MUCH OF THE REST OF THE WORK WEEK. ESPECIALLY FOR SHELTERED VALLEYS AND LOCATIONS NEAR RELATIVELY WARMER BODIES OF WATER. TRANQUIL CONDITIONS EXPECTED TUESDAY NIGHT WITH HIGH PRESSURE REMAINING IN CONTROL.
903 PM EST MON NOV 2 2015 HIGH PRESSURE WILL CREST OVERHEAD TONIGHT.
IT SHOULD BE NOTED THIS WOULD BE MORE OF A CONDITIONAL THREAT IF THE LOW CLOUD DECK IS MORE PREVALENT.
706 PM EST MON NOV 2 2015 HIGH PRESSURE OVER THE REGION WILL MOVE EAST LATE TONIGHT.
THESE MVFR BASES SHOULD BE INTERMITTENT AS A RAGGED AREA OF CLOUD DECKS ROTATES AROUND CLOSED LOW TO THE EAST. AS THE COOLER AIR DEEPENS IN THE BACK DOOR. THE WARMER TEMPS WILL FILTER BACK INTO MIDWEEK WITH PARTLY CLOUDY CONDITIONS DURING THIS TIMEFRAME.
