722 PM EDT FRI AUG 7 2015 WEAK HIGH PRESSURE BUILDS FROM THE NORTH TONIGHT.
HUSTON A LOW PRESSURE SYSTEM OVER NORTHERN NEVADA WILL ARRIVE TONIGHT. RAIN CHANCES ARE LESS AROUND THE STANLEY/CHALLIS AREAS BECAUSE OF THE TRACK OF THE LOW WHICH SHOULD PASS THROUGH SOUTHEAST IDAHO. THE LOW WILL EXIT THE REGION SATURDAY AFTERNOON. AN UPPER LOW OVER THE GREAT BASIN THIS AFTN WILL MOVE NE INTO SRN IDAHO OVERNIGHT AND ON SATURDAY. AN UPPER LOW OVER THE GREAT BASIN WILL MOVE INTO SOUTHERN IDAHO OVERNIGHT AND ON SATURDAY. EXTENSIVE CLOUD COVER AND RAIN WILL RESULT IN COOLER TEMPERATURES FOR SATURDAY.

850 PM MDT FRI AUG 7 2015 MONSOONAL MOISTURE PUSHED NORTHWARD BY A LARGE UPPER LOW OVER NEVADA WILL CONTINUE TO SPREAD INTO THE AREA TONIGHT. WE WILL START TO SEE INCREASING CLOUDS TONIGHT AS UPPER LOW OVER THE GREAT BASIN MOVES THIS WAY. CLOUD COVER AND WAA AHEAD OF APPROACHING SYSTEM WILL KEEP THE OVERNIGHT HOURS WARMER THAN LAST NIGHT. AS THE UPPER LOW APPROACHES FROM THE SOUTHWEST LATE TONIGHT IT WILL INDUCE SURGE OF SUBTROPICAL MOISTURE FROM THE SOUTH.

FORECAST MODELS ARE IN GENERAL AGREEMENT THAT AN UPPER LOW WILL THEN DESCEND SOUTHWARD ALONG THE PACIFIC COASTLINE FROM THE GULF OF ALASKA AND EVENTUALLY PROGRESS TOWARDS CALIFORNIA BY MIDWEEK. THE GFS AND EUROPEAN MODEL STALL THE UPPER LOW JUST OFFSHORE OF THE CALIFORNIA/OREGON STATELINE MIDWEEK AND THEN LIFT THE LOW BACK IN THE WESTERLIES AS IT SHIFTS DOWNSTREAM. HIGH PRESSURE BUILDS BEHIND THIS AND WILL LEAD TO SLIGHTLY WARMER TEMPERATURES TOWARDS THE END OF THE WORK WEEK. KSFO BRIDGE APPROACH.

Upper level ridge was beginning to build into the area from the southwest along with the return of the hotter temperatures and increased surface dew points. The upper level ridge will remain in place over the weekend and will see temperatures reach the low to mid 90s over the eastern half of the Ozarks and mid to upper 90s over the western portion into extreme southeast Kansas. With dewpoints in the low to mid 70s, we will see heat index values over the western half of the CWA climb above the threshhold for a heat advisory (105 deg F).

IT THEN APPEARS THAT THERE SHOULD BE A LULL IN THE THUNDERSTORM ACTIVITY AT SOME POINT THIS EVENING AS WE AWAIT THE ARRIVAL OF THE BETTER CONVERGENCE ALONG A COLD FRONT. HOWEVER LOCATIONS ACROSS NW OHIO WILL SEE THE FRONT PASS BEFORE SUNRISE WHICH WILL ALLOW LOWS TO DIP TO THE LOWER 60S. COLD FRONT WILL BE MOVING ACROSS THE AREA THURSDAY EARLY AFTERNOON.

WHICH WILL PROMOTE RADIATIONAL COOLING WITH LOW TEMPERATURES IN THE LOW TO MID 50S. NORTHWESTERLY FLOW ALOFT WILL TURN MORE ZONAL ON THURSDAY WHICH WILL HELP ESTABLISH A LEE SIDE TROUGH ACROSS THE PANHANDLE REGION. THIS WILL CAUSE SOUTHERLY FLOW TO RETURN TO THE AREA WITH WARMER TEMPERATURES AND INCREASING MOISTURE.
1120 AM MDT WED AUG 19 2015 HIGH PRESSURE IS BUILDING ALOFT AND THE AIR MASS WILL WARM AND DRY TODAY. HIGH PRESSURE IS BUILDING OVER OVER THE REGION AND THE AIR MASS WILL REMAIN DRY AND STABLE.

MODEST MOISTURE RETURN/SURFACE DEW POINTS IN THE LOWER 50S/RESULTING IN SBCAPE OF UP TO 1500 J/KG IN A NARROW AXIS GENERALLY FROM KMCK TO KGLD COMBINED WITH DEEP LAYER SHEAR OF AROUND 40KTS SUGGEST A RISK OF SEVERE STORMS.
A DEEP WESTERN ATLANTIC RIDGE STRETCHES WEST ACROSS THE NORTHERN FLORIDA PENINSULA. THE WAVY SOUTHERN PERIPHERY OF THIS RIDGE CARRIES PULSES IN MOISTURE AND WIND SPEED. THESE PULSES CAN BE INFERRED BY THE LOW LEVEL VORTICITY ANALYSES FROM CIMSS. TEMPERATURES ARE IN THE LOWER 90S.
