FRONTAL BOUNDARY WILL MOVE NORTH OF THE REGION LATE TONIGHT AND EARLY THURSDAY AS LOW PRESSURE MOVES NORTHEAST TOWARDS THE GREAT LAKES REGION. WITH SHOWERS AND THUNDERSTORMS DEVELOPING AGAIN ON THURSDAY AS A COLD FRONT ASSOCIATED WITH THE LOW SINKS BACK INTO THE AREA. THIS LOW WILL PASS TO OUR NORTH THURSDAY.
323 PM CDT WED JUL 8 2015 A WEAK TROUGH AND THE ALSO WEAK FRONTOGENESIS ALONG IT HAS SERVED TO GENERATE SOME WEAK SHOWERS OVER NORTHERN MINNESOTA TODAY. BUT THE LOW LAYERS ARE VERY DRY AND THE RADAR ECHOES ARE OFTEN WEAK AND PRODUCE LITTLE MORE THAN SOME LIGHT RAIN SHOWERS OR SPRINKLES FOR MOST LOCATIONS. MORE SUNSHINE AND WARMER TEMPERATURE ALOFT WILL ALLOW HIGHS TO RISE INTO THE UPPER 70S AND LOWER 80S.
130 PM EDT WED JUL 8 2015 THE COLD FRONT THAT MOVED THROUGH YESTERDAY WILL STALL JUST SOUTH OF THE AREA TODAY. A WAVE OF LOW PRESSURE WILL RIDE ALONG THE FRONT ON THURSDAY.
ACROSS THE LOWER LATITUDES. THE AXIS OF A TROPICAL UPPER TROPOSPHERIC TROUGH(TUTT) IS ORIENTED FROM THE NORTH CENTRAL GULF OF MEXICO. A WELL DEFINED UPPER LOW. SCATTERED CLUSTERS OF THUNDERSTORMS ARE APPROACHING THE BAHAMAS IN ASSOCIATION WITH THE AFOREMENTIONED UPPER LOW. SOUTH FLORIDA AND THE KEYS ARE BETWEEN THE TROUGHS AT THE SOUTHERN EDGE OF AN UPPER RIDGE. AT THE SURFACE AND IN THE LOWER TO MID LEVELS. COMBINATION OF LOWER LEVEL TROUGHING IN THE CARIBBEAN SEA WITH DECENT RIDGING SET IN TO THE NORTH OF THE KEYS OVER THE PENINSULA. BREEZES ARE ALSO BACKED MORE TO EAST IN RESPONSE TO AN APPROACHING UPPER LOW IN TANDEM WITH A VERY WEAK LOW LEVEL IMPULSE WHICH SHOULD MOVE THROUGH THE KEYS LATER THIS EVENING AND DURING THURSDAY MORNING. LOOKS LIKE THE SURFACE RIDGING WILL BE A LITTLE CLOSER TO THE KEYS.
315 PM CDT WED JUL 8 2015 A COOLER THAN NORMAL PERIOD CONTINUES WITH QUIET WEATHER UNDER THE INFLUENCE OF HIGH PRESSURE. AS THE TROUGH APPROACHES. POST-TROUGH TONIGHT.

THIS DRYING TREND WILL CONTINUE OVERNIGHT AND INTO TOMORROW AS HIGH PRESSURE CONTINUES TO BUILD WEST.
Strong high pressure will return to the Inland Northwest today bringing more hot and hazy weather. Rather benign weather expected today under high pressure with just a slight chance of thunderstorms developing over the east slopes of the Cascades where some cumulus clouds are building on remnant moisture from last nights thunderstorms. /Kelch 18Z TAFS: High pressure will strengthen over the region today and linger into Thursday.
251 PM EDT WED JUL 8 2015 THE COLD FRONT WILL STALL NEAR THE MASON-DIXON LINE TODAY. CL STRONG LOW PRESSURE SYSTEM ADVANCING TOWARDS THE REGION WILL HELP SHIFT THE BOUNDARY NORTHWARDS AND PRODUCE SHOWERS AND THUNDERSTORMS. NEAR THE CENTER OF THE LOW. HIGH PRESSURE DEVELOPS AMID MOSTLY ZONAL FLOW.
145 PM EDT WED JUL 8 2015 THE COLD FRONT WILL STALL NEAR THE MASON-DIXON LINE TODAY. CHANCES FOR RAIN DIMINISH TONIGHT AS THE NEXT LOW PRESSURE SYSTEM MOVES TO NORTHEASTERN INDIANA BY THURSDAY MORNING. HIGH PRESSURE WILL BUILD INTO THE REGION THURSDAY NIGHT.
1226 PM CDT WED JUL 8 2015 WATER VAPOR IMAGERY SHOWING A BROAD TROUGH/ZONAL FLOW FROM EAST OF THE NORTHERN ROCKIES THROUGH THE UPPER MISSISSIPPI RIVER VALLEY AND THROUGH THE GREAT LAKES. TO THE LOWER/MIDDLE 50S ELSEWHERE. A WEAK MID-LEVEL TROUGH WILL DRIFT ACROSS FROM THE NORTHERN PLAINS INTO NORTHERN MN/WI TODAY. WE WILL BE ON THE SOUTHERN INFLUENCE OF THIS TROUGH WITH MODEL SOUNDINGS SHOWING ONLY SOME CIRRUS AND SCATTERED/BROKEN SHALLOW CUMULUS.
TSTRM COVERAGE LOOKS LESS GIVEN COOLER TEMPS EXPECTED BUT SOME SHOULD FORM IN THE AFTERNOON. MODEL SOUNDINGS CONTINUE TO BE DEEPLY SATURATED ACROSS MUCH OF THE AREA THROUGH THURSDAY NEAR A WEAK UPPER LOW THAT IS MIGRATING VERY SLOWLY EASTWARD ACROSS SOUTHERN WYOMING AND NORTHERN COLORADO. THEN CHANCE POPS MOST EVERYWHERE THURSDAY BEFORE TAPERING THEM OFF THURSDAY EVENING AS THE WEAK MIDLEVEL CIRCULATION SLIDES OFF TO THE EAST AND WE SEE MODEST MID/UPPER RIDGING WORKING IN FROM THE SOUTHWEST.

THE TRACK OF THIS LOW WILL HELP TO DETERMINE EXACTLY WHERE THE AXIS OF HEAVIEST RAINFALL WILL OCCUR.
1133 PM CDT SAT OCT 24 2015 AT H5 CLOSED LOW JUST OFF PACIFIC NORTHWEST COAST. HUDSON BAY LOW WITH TROUGH INTO THE NORTHERN MISSISSIPPI VALLEY AND REMNANTS OF PATRICIA MOVING ACROSS MEXICO. AT THE SURFACE COLD FRONT FROM GREAT LAKES INTO TEXAS GULF COAST.
1155 PM CDT SAT OCT 24 2015 Quiet conditions expected across central and southeast Illinois overnight as high pressure builds into the area. A cold front just east of a Paris to Salem line will push through southeast IL the rest of this afternoon and give a chance of showers and isolated thunderstorms until supper time. Breezy wnw winds of 15 to 25 mph behind cold front this afternoon and early evening to veer NNW overnight and diminish to 5 to 10 mph as 1024 mb high pressure over the Great Plains settles into IA and northern MO by sunrise Sunday. Lows overnight mostly in the lower 40s over central IL, ranging from the upper 30s to near 40F nw of IL river to the mid 40s in southeast IL.
/ISSUED 352 PM CDT SAT OCT 24 2015/ (Tonight and Sunday) An upper trough over far west Texas into northern Mexico will progress east into our area tonight. Gusty north winds are occurring in the wake of the cold frontal passage, and temperatures have fallen into the 50s behind the front. Some cloud cover will remain over some of our eastern counties, where there is a lingering slight chance of showers Sunday morning until the trough axis shifts to the east.
548 PM MDT SAT OCT 24 2015 DRY AND MILD WEATHER WILL HOLD OVER THE CWA THROUGH SUNDAY AS A TRANSITORY UPPER RIDGE PASSES ACROSS.
19Z water vapor imagery shows an upper trough over northern Mexico with subtropical moisture streaming north through the southern plains. At the surface, ridging has built into western KS with dry air advecting in the area from the northwest. Any weak perturbation in the northern stream simply shouldn't have any moisture to work with,and the upper trough over Mexico is progged to remain over the southern plains. Feel reasonably confident that temps will remain above freezing as bias corrected guidance is tending to pull temps slightly warmer. So feel like if the forecast is going to be off, it may be to the warmer side due to high clouds remaining over the area. While I'm not anticipating widespread freezing temps, have gone ahead and issued a frost advisory for north central KS where some patchy frost is possible around dawn.
831 PM EDT SAT OCT 24 2015 SHOWERS TONIGHT WILL BE FOLLOWED BY A DRY AND COOLER SUNDAY. HIGH PRESSURE WILL GIVE A DRY START TO THE WORK WEEK.

COOLER AIR WILL CONTINUE TO MOVE INTO THE REGION OVERNIGHT BEHIND A COLD FRONT. DRIER AIR BEHIND THIS COLD FRONT WILL ALLOW FOR THE LOW CLOUDS ACROSS THE AREA TO DIMINISH LATE TONIGHT INTO EARLY SUNDAY MORNING. ADDITIONAL POCKETS OF LIGHT RAIN/DRIZZLE HAVE ALSO DEVELOPED ACROSS SOUTHERN LOWER MICHIGAN/NORTH CENTRAL INDIANA IN CLOSER PROXIMITY TO PASSING MID LEVEL TROUGH. MODELS REMAIN IN GOOD AGREEMENT ON THE EVOLVING LARGE SCALE PATTERN WITH A HIGH AMPLITUDE TROUGH DIGGING INTO THE CENTRAL CONUS AND ABSORBING TROPICAL MOISTURE PLUME ASSOCIATED WITH THE REMNANTS OF PATRICIA.
