HIGH PRESSURE WILL MOVE BACK INTO THE REGION LATE TONIGHT RESULTING IN DRY AND WARM WEATHER THROUGH THE WEEKEND. HIGH PRESSURE AT THE SURFACE WILL BUILD SOUTHWARD FRIDAY NIGHT AND SETTLE OVER THE REGION THROUGH THE WEEKEND. ALOFT THE RIDGE WILL REGAIN CONTROL OF THE WEATHER PATTERN AND INHIBIT CONVECTION TO DEVELOP OVER THE REGION THROUGH THE WEEKEND.

STRONG UPPER LEVEL RIDGE WILL REMAIN OVER THE NORTHEAST THROUGH MID WEEK BEFORE GETTING FLATTENED BY AN UPPER LEVEL WAVE.
1236 AM CDT FRI SEP 4 2015 HIGH PRESSURE CONTINUES OVER THE AREA. THE UPPER RIDGE HAS BUILT IN MORE OVER THE REGION AND THIS WILL BE A NEGATIVE FACTOR. TEMPS ARE ON TRACK TO REACH THE LOWER TO MID 90S.

A MAINLY CLEAR AND SEASONABLY COOL NIGHT REMAINS ON TRACK AS HIGH PRESSURE CONTINUES TO BUILD SOUTH AND EAST INTO THE REGION. THE RIDGE RETURNS ON FRIDAY AFTER MARGINALLY BREAKING DOWN DUE TO THE WEAK FRONT TODAY. EXPECT SLIGHTLY COOLER TEMPS FRIDAY AS THE NORTHERLY WINDS CONTINUE TO BRING MARGINAL COLD AIR ADVECTION.
344 AM EDT FRI SEP 4 2015 HIGH PRESSURE OVER EASTERN CANADA DRIFTS TO THE SOUTH TONIGHT. MUCH COOLER AND DRIER AIR BUILDS IN FROM THE NORTH. AND HIGHS WILL TOP OFF IN THE LOW TO MID 80S.

408 AM CDT FRI SEP 4 2015 Ridge of high pressure aloft will remain in control of things through the holiday weekend with a near persistence forecast continuing.
255 AM CDT FRI SEP 4 2015 The upper ridge will remain over the region even though an upper trough digs across the NW part of the country the next few days. The best it will be able to do is flatten out the top of the ridge as it moves east. Still getting lots of high clouds streaming over the area as Pacific moisture gets pulled around the west side of the ridge. A cold front is still on track for next Thursday will result in at least a couple days of cooler temps. could see these again the next few days favoring the higher elevations.
Deep northwest flow will continue as the local region resides on the backside of a broad upper trough. Highs will be in the lower 90s inland and around 90 along the coast.

303 AM CDT FRI SEP 4 2015 SPRAWLING UPPER-LEVEL RIDGE EXTENDING FROM THE SOUTHERN PLAINS INTO THE WESTERN GREAT LAKES WILL CONTINUE TO DOMINATE THE WEATHER ACROSS CENTRAL ILLINOIS TODAY. LEADING TO MOSTLY SUNNY SKIES WITH HIGH TEMPERATURES ONCE AGAIN TOPPING OUT IN THE LOWER TO MIDDLE 90S. THE ONLY POTENTIAL FLY-IN-THE-OINTMENT WILL BE AN UPPER LOW SPINNING OVER MICHIGAN. HOWEVER A WELL-DEFINED CIRCULATION IS NOTED ROTATING AROUND THE LOW ACROSS EASTERN WISCONSIN.
/issued 222 PM CDT THU SEP 3 2015/ An upper ridge will continue to be the dominant feature over the forecast area through the weekend which will result in high temperatures remaining above normal. However, a plume of mid and upper level moisture will continue to impinge upon the higher terrain, and allow for a slight chance of thunderstorms this afternoon and evening, and again Friday. The mentioned plume of moisture will spread northward over the weekend, while the ua ridge will build a little further westward. Will still carry a low chance of thunderstorms over the higher terrain both days though as surface dewpoints will continue to rise.
TEMPERATURES WILL REMAIN MUCH COOLER THAN NORMAL TODAY, AS AMPLE CLOUDS AND RAIN SHOULD KEEP SOLAR HEATING TO A MINIMUM. AN UPPER LEVEL LOW, CURRENTLY LOCATED OVER THE SEATTLE AREA, WILL DROP SOUTH TODAY, AND TAKE POSITION OVER OREGON BY THIS AFTERNOON.
TODAY AND TONIGHT THE ABOVE NORMAL TEMPERATURES AND HIGHER HUMIDITY VALUES WILL PERSIST THROUGH THE DAY UNDER THE INFLUENCE OF A WEAKENING HIGH PRESSURE SYSTEM. ISOLATED TO SCATTERED SHOWERS AND A FEW THUNDERSTORMS CAN BE EXPECTED THIS AFTERNOON INTO EARLY EVENING PARTICULARLY IN THE HIGHER TERRAIN OF THE MOUNTAINS AND PLATEAU.

THE RIDGE RETURNS ON FRIDAY AFTER MARGINALLY BREAKING DOWN DUE TO THE WEAK FRONT TODAY. EXPECT SLIGHTLY COOLER TEMPS FRIDAY AS THE NORTHERLY WINDS CONTINUE TO BRING MARGINAL COLD AIR ADVECTION.
ALL TAF SITES WILL BE AFFECTED THE STORMS THOUGH THE SOUTHERN HALF OF THE AREA WILL HAVE THE HIGHER AREAL COVERAGE.
While the upper-level ridge will keep the hot and dry conditions in place across most of the area, increasing moisture and instability will provide an opportunity for isolated convection this afternoon, primarily south of a Sonora to Brady line.
TONIGHT-SAT: THE UPPER RIDGE WILL CONTINUE TO DOMINATE THE WEATHER PATTERN FOR TONIGHT THROUGH SAT AS THE RIDGE AXIS REMAINS ACROSS THE PLAINS. AS THE LEE TROUGH REMAINS OVER EXTREME WRN KS. POSSIBLY EVEN TWEAKING THOSE NUMBERS A LITTLE WARMER STILL.
325 AM PDT FRI SEP 4 2015 A low pressure system over the Pacific Northwest will bring a chance of showers or thunderstorms to the northern mountains with partly cloudy skies and well below normal temperatures elsewhere.

HIGH PRESSURE WILL ENSURE FAIR AND DRY WEATHER FOR LABOR DAY WEEKEND. THERE IS AN UPPER LEVEL LOW OVER LWR MI WHICH IS MAINLY A WEAKNESS IN THE MASSIVE RIDGE OVERHEAD. THE MAXES WILL PROBABLY STAY A FEW DEGS F COOLER AS WELL. THE GFS IS NOT SO BULLISH ON THE LOW LEVEL MOISTURE. IT STILL HINTS AT SOME LOWER CLOUDS /BELOW 8H/ BUT IS MORE NORTHEASTERLY WITH THE WINDS ON THE SRN PERIPHERY OF THE HIGH. WILL KEEP IT MORE CLOUDY AND COOLER IN THE FIRST PART OF THE DAY AND KEEP MAXES SHORT OF GFS-MOS GUIDANCE.
432 AM CDT FRI SEP 4 2015 A SOUTHWESTERLY FLOW ALOFT WILL ALLOW SUB-TROPICAL MOISTURE TO ADVECT NORTHEAST ACROSS THE PANHANDLES TODAY THROUGH THE WEEKEND AS AN UPPER HIGH REMAINS OVER NORTH AND CENTRAL TEXAS.

319 AM CDT FRI SEP 4 2015 General high pressure at the sfc, and a ridge axis aloft, will continue to be the persistent pattern for the PAH forecast area in the short term. We thought the MAV MOS numbers may be a bit warm for peak afternoon temps, but highs in the lower half of the 90s should occur over the next three days.
EXPECT WAVE TO LIFT NORTH/NORTHEAST AHEAD OF APPROACHING LOW PRESSURE SYSTEM AND GIVEN THE GENERALLY UNSTABLE AIRMASS IN PLACE. KEPT TEMPS SLIGHTLY COOLER IN THE NORTHWEST WHERE CLOUDS MAY HELP KEEP CONDITIONS COOLER. THE WEAK UPPER LEVEL LOW CENTERED OVER LOWER MICHIGAN WILL REMAIN SOMEWHAT PROBLEMATIC THROUGH TONIGHT BEFORE FINALLY DEPARTING TO THE EAST. NOT COMPLETELY CONFIDENT THAT A REPEAT WILL NOT OCCUR AGAIN TONIGHT THOUGH THE CIRCULATION CERTAINLY IS WEAKENED BY THAT TIME AND THE UPPER RIDGE WILL BE PUSHING FURTHER INTO THE AREA.

LOOKING FOR HIGHS IN THE 40S AND 50S AND TRIED TO KEEP THE SNOW PACK AREAS A BIT COOLER THAN SURROUNDINGS.

The center of high pressure that was over Central/Southern Plains overnight had shifted east southeast toward the Mississippi River Valley by mid this morning. winds gusts should be a little weaker with gusts of 10 to near 20 mph as the far western edge of high pressure resides over these locations the longest. Downslope flow with gusty southerly winds will aid afternoon temperatures to be warmer this afternoon with highs in the 60s/low 70s possible. Locations along and west of Highway 75 are expected to have the greater fire danger conditions as these locations should have the higher wind gusts.
Warmer air with this first surge of moisture will keep snow levels above 7000 feet (or all pass levels) Saturday.
