As Thursday evening approaches, so will a cold front from the north, sliding across the region tomorrow night. Temperatures tomorrow will warm a few more degrees than today, reaching near and into the lower 80s area wide. Behind the front, look for much cooler temps, dropping back off into the mid to upper 60s on Friday and dipping down into the mid 40s Friday night.
127 AM EDT THU OCT 8 2015 HIGH PRESSURE WILL BUILD INTO THE REGION OVERNIGHT THROUGH FRIDAY. A WEAK COLD FRONT WILL APPROACH FROM THE NORTHWEST THIS WEEKEND. HIGH PRESSURE WILL BUILD INTO THE REGION FROM THE NORTH OVERNIGHT. ANOTHER MOSTLY SUNNY DAY IS EXPECTED AS A RIDGE OF HIGH PRESSURE AT THE SURFACE SETTLES OVER SOUTH CAROLINA. BUT THAT SHOULD NOT PREVENT TEMPERATURES FROM GETTING INTO THE LOWER TO MID 80S. SO I CANT RULE OUT THE SLIGHT CHANCE OF AN AFTERNOON OR EVENING SHOWER AS A COLD FRONT APPROACHES FROM THE NORTHWEST.
COOLER AIR WILL THEN FILTER INTO THE REGION FOR THURSDAY WITH TEMPERATURES ABOUT 10 DEGREES COOLER THAN TODAY. THE MODELS SHOW ANOTHER SHORT WAVE TROUGH SPREADING CLOUDS ALONG WITH SOME SMALL CHANCES OF LIGHT RAIN TO OUR SOUTHWEST CWA TONIGHT AND THURSDAY. WARMER AIR WILL RETURN TO THE REGION. EXPECT HIGHS IN THE MID 60S EAST TO THE LOWER 70S WEST. WE WILL ALSO HAVE MILD LOWS ON FRIDAY NIGHT IN THE UPPER 40S TO THE LOWER 50S UNDER MOSTLY CLEAR SKIES.
105 AM EDT THU OCT 8 2015 A WEAK COLD FRONT CONTINUES MOVING ACROSS THE REGION THIS EVENING WITH A FEW SPRINKLES OVER NORTHERN NEW YORK. HIGH PRESSURE RETURNS TONIGHT AND THURSDAY WITH QUIET AND DRY WEATHER BEFORE A COLD FRONT WILL BRING WIDESPREAD SHOWERS TO THE NORTH COUNTRY ON FRIDAY.
UPPER RIDGE AXIS NEAR AND ALONG THE LOWER MISSISSIPPI RIVER VALLEY THIS MORNING WILL CONTINUE TO DRIFT EAST AND FLATTEN THROUGH TONIGHT LEADING TO MOSTLY SUNNY SKIES AND MILD TEMPS DURING THE DAY. AS FOR TEMPS WILL LEAN TOWARDS THE WARMER GUIDANCE FOR HIGHS TODAY DUE TO BETTER SUBSIDENCE IN THE BOUNDARY LAYER ALONG WITH PLENTY OF SOLAR HEATING. FOR TONIGHT WILL LEAN TOWARDS THE WARMER MAV TEMPS DUE TO A LITTLE UNCERTAINTY WITH THE EASTERN EXTENT OF THE HIGH BASE CLOUDS MENTIONED ABOVE.
with a cold front trailing into the Northern Rockies. The low is progged to track into the Great Lakes later today. With boundary remaining well to the W/NW through this afternoon, ample sunshine and gusty southwesterly winds will push high temperatures into the lower 80s. Cold front will be interacting with an unseasonably warm/moist airmass as it arrives across central Illinois tonight, with forecast soundings indicating precipitable water values two standard deviations above normal for this time of year at around 1. Main story will be the considerably cooler weather with afternoon highs remaining in the 60s. High pressure will provide chilly conditions with lows in the middle 40s Friday night, but a marked warming trend will develop over the weekend as it quickly shifts off to the east.
151 AM EDT THU OCT 8 2015 HIGH PRESSURE CENTERED OVER THE UPPER GREAT LAKES WILL MOVE EAST BUT CONTINUE TO EXTEND INTO THE OHIO VALLEY THROUGH THURSDAY. A COLD FRONT WILL APPROACH FROM THE NORTHWEST THURSDAY NIGHT AND MOVE ACROSS THE REGION FRIDAY. HIGH PRESSURE WILL BUILD INTO THE AREA OVER THE WEEKEND. SHADED TOWARDS COOLER NUMBERS. THERE IS SOME SUGGESTION OF A PSEUDO-WARM FRONT LIFTING NORTHEAST. 12Z GUIDANCE IS IN REASONABLY GOOD AGREEMENT IN THE MOVEMENT OF A COLD FRONT TOWARDS AND THEN THROUGH THE AREA THURSDAY NIGHT AND FRIDAY. INCREASING MOISTURE AND CLOUDS ALONG WITH SOUTHERLY WINDS SHOULD ALLOW FOR LOWS A BIT WARMER THAN GUIDANCE THURSDAY NIGHT.
EXPECT A DOME OF HIGH PRESSURE TO INFLUENCE THE GREAT BASIN RESULTING IN ABOVE NORMAL TEMPERATURES.

A MORE VIGOROUS TROUGH WILL APPROACH FROM THE NORTHWEST AND AFFECT NORTHERN IOWA AFTER MIDNIGHT. THE APPROACH OF THIS TROUGH WILL ALSO CAUSE SURFACE WINDS TO COME AROUND TO SOUTH SOUTHWEST LATE TONIGHT AND RESULT IN GRADUALLY INCREASING AND THICKENING CLOUDS. A LOW CHANCE FOR PRECIPITATION IS POSSIBLE OVER THE FAR SOUTH BEFORE PROFILES QUICKLY DRY OUT AS HIGH PRESSURE SETTLES INTO THE REGION THURSDAY NIGHT AND FRIDAY. TEMPERATURES WILL BE COOLER ON FRIDAY HOWEVER THE COMBINATION OF DRY AIR AND LOTS OF SUNSHINE WILL PUSH TEMPERATURES ABOVE GUIDANCE WITH HIGHS GENERALLY IN THE 60S.

COOLER TEMPERATURES STILL ON TARGET FOR FRI MAXES. COLD FRONT MOVES THROUGH ON SUN NIGHT DRY DUE TO LACK OF SUFFICIENT RETURN MOISTURE. WOULD NOT BE SURPRISED IF TEMPERATURES END UP WARMER THAN CURRENTLY FORECAST.

SCT SHOWERS AND THUNDERSTORMS WILL ACCOMPANY THE COLD FRONT THROUGH THE EVENING HOURS.

FORCING INCREASING THROUGH THE EVENING AS THE FRONT APPROACHES WILL ALLOW FOR SHOWER DEVELOPMENT ALONG THE EASTERN RIDGES BORDERING VA. HEADING INTO FRIDAY MORNING SHORT TERM MODELS HAVE THE APPROACHING COLD FRONT MOVING IN A BIT QUICK WITH SHOWERS AND POSSIBLE THUNDERSTORMS DEVELOPING AND MOVING INTO THE AREA BY 12Z OR JUST AFTER ON FRIDAY MORNING. THEY ALL DEPICT A DIGGING TROUGH MOVING THROUGH THE OHIO AND TENNESSEE VALLEY AT THE START OF THE WEEKEND. THIS WILL BE FOLLOWED BY RISING HEIGHTS FROM THE SOUTHERN PLAINS AND THE WEAKENING OF THAT TROUGH.

Strong low pressure will shift east across Neb with a trailing dryline reaching the Flint Hills region of KS by early evening 7pm/31-00z. Will still take some work to get precip going with sfc dew points still in the low/mid 30s. The high res ARW and NMM are not too bullish in moving the convection too far off the dryline initially so it looks like the best chance for severe storms late today and this evening will be over the western cwfa. As the low continues off to the east, a cold front catches up to the dryline and moves east through the cwfa overnight.
High pressure over the eastern Pacific will gradually build across the area the remainder of the week for a return to dry and milder weather. Moisture and instability wrapping around the low over the Rockies may bring a few showers to the Sierra south of Tahoe into this evening.
