NATIONAL WEATHER SERVICE BILLINGS MT
232 PM MDT FRI MAY 19 2006
.SHORT TERM...VALID FOR SAT AND SUN...
SUMMER LIKE WEATHER OVER THE AREA WITH A MONSOONAL SURGE OF
MOISTURE TODAY BRINGING ISOLATED THUNDERSTORM ACTIVITY THIS
AFTERNOON AND EVENING. DRIER AIR PUSHING INTO SOUTH CENTRAL
MONTANA APPEARS TO BE RETARDING SOME OF THE CONVECTION BUT DEEPER
MOISTURE OVER THE CENTRAL AND EASTERN ZONES IS SUPPORTING SOME
DEVELOPMENT. BREAKS IN THE CLOUDS ARE SUPPORTING LATE DAY WARMING
SO SHOULD BE ANOTHER MILD NIGHT WITH DEBRIS CLOUDS HOLDING IN SOME
WARMTH. SHORTWAVE CURRENTLY OVER CENTRAL MONTANA TRACKING SLOWLY
EAST AND GENERATE ENOUGH LIFT TO AID AIRMASS TYPE THUNDERSTORM
ACTIVITY AND DO NOT EXPECT MUCH ORGANIZATION TO THE CELLS. RIDGE
SHARPENS ON SATURDAY AS THE SHORTWAVE DEPARTS AND THIS SHOULD
SUPPORT LESS CLOUD COVER AND A REBOUND IN TEMPERATURES.
HOWEVER...THE RIDGE IS STARTING AN EASTWARD MIGRATION AND
SOUTHWEST FLOW SATURDAY AFTERNOON OVER SOUTHWEST MONTANA SHOULD
ALLOW A ROUND OF THUNDERSTORMS TO DEVELOP OVER THE TERRAIN AND
MOVE ACROSS THE WESTERN PORTIONS OF THE AREA IN THE AFTERNOON.
WHILE LOOKING FOR ONLY A 1 DEGREE INCREASE AT 700 MB THE BETTER
SUNSHINE SHOULD SUPPORT A 5 DEGREE RISE IN TEMPERATURES WITH LATE
AFTERNOON CONVECTION PROBABLY KEEPING THE 90S FROM BEING REACHED.
OTHER WEATHER FEATURE OF NOTE ON SATURDAY AND SATURDAY EVENING IS
THE THERMAL SURFACE TROF STARTS MIGRATING EASTWARD WITH THE RIDGE
AND THIS ALLOWS A LOW LEVEL JET TO FORM OVER THE EASTERN PLAINS
SATURDAY NIGHT. AT THIS POINT DO NOT EXPECT THE LATE AFTERNOON
CONVECTION TO REACH THAT FAR EAST BUT IT WILL HAVE TO BE WATCHED
FOR POSSIBLE SHEAR INTERACTIONS. DO NOT THINK THAT DEWPOINT
ADVECTION OVER THE EAST WILL BECOME AN ISSUE UNTIL SUNDAY JUST
BECAUSE THE STRONGEST CAP SHOULD BE OVER SOUTHEAST MONTANA
SATURDAY NIGHT. SUNDAY SHOWS A SIGNIFICANT ADVECTION OF SURFACE
MOISTURE UP THE HIGH PLAINS WITH CAPE VALUES ON THE INCREASE.
UNFORTUNATELY NOT GOOD MODEL AGREEMENT BETWEEN THE NAM ON GFS ON
WHERE THE LOW LEVEL MOISTURE WILL BE. IF SUNDAY SETS UP AS PROGGED
BY THE NAM...SIGNIFICANT POTENTIAL WILL EXIST FOR THE DEVELOPMENT
OF SUPERCELL THUNDERSTORMS. WILL CURRENTLY COVER WITH AFTERNOON
THUNDERSTORMS. POSITIONING OF THERMAL TROF SHOULD ENSURE SUNDAY IS
CLOSE TO SATURDAY TEMPS WITH SOME HEDGING FOR DEBRIS CLOUDS.
BORSUM
.LONG TERM...VALID FOR MON...TUE...WED...THU...FRI...
NOT MANY CHANGES FROM PREVIOUS EXTENDED PACKAGE EXCEPT TO FINE
TUNE SOME GRID AREAS BUT OVERALL FORECAST REMAINS IN GOOD SHAPE.
LARGE TROUGH STILL EXPECTED TO MOVE ACROSS THE FORECAST AREA
MONDAY WITH STRONG SOUTHERLY UPPER LEVEL FLOW ASSOCIATED WITH IT.
AT THE SAME TIME...A STRONG COLD FRONT PROGGED TO SWEEP ACROSS
THE AREA MONDAY EVENING/NIGHT. LOOKS LIKE A GOOD DEAL OF
INSTABILITY AND MOISTURE ASSOCIATED WITH THESE FEATURES TO
CONTINUE WITH A SLIGHT CHANCE OF POPS FOR MOST OF MONDAY WITH
HIGH CHANCES BY LATE MONDAY AFTERNOON AND CONTINUING OVERNIGHT.
MONDAY LOOKS TO BE THE LAST HOT DAY FOR THE REMAINDER OF THE WEEK
AS A THERMAL RIDGE WILL BE OVER THE AREA ALONG WITH STRONG
COMPRESSIONAL HEATING AHEAD OF THE FRONT. THE POSSIBILITY EXISTS
FOR SOME OF THE THUNDERSTORMS TO BE SEVERE...ESPECIALLY ACROSS
THE FAR EASTERN ZONES WHERE THE HIGHEST CAPE AND INSTABILITIES
WILL EXIST.
UNSETTLED SOUTHWEST FLOW ALOFT STILL PROGGED TO SET UP FOR THE
REMAINDER OF THE WEEK BRINGING A SLIGHT CHANCE FOR SHOWERS AND
THUNDERSTORMS EACH DAY. A STRONGER TROUGH IS POISED TO MOVE OVER
THE STATE FRIDAY AND INTO EARLY NEXT WEEK. TEMPERATURES STARTING
TUESDAY AND CONTINUING THROUGH THE REMAINDER OF THE PERIOD WILL BE
COOLER AND MORE NORMAL FOR MAY. HOOLEY
&&
.AVIATION...
A WEAK UPPER LEVEL DISTURBANCE WILL CONTINUE TO MOVE OVER THE
FORECAST AREA THIS AFTERNOON THROUGH THIS EVENING BRINGING THE
CHANCE FOR SHOWERS AND THUNDERSTORMS. ANY THUNDERSTORM MAY
PRODUCE BRIEF HEAVY RAIN RESULTING IN MVFR CONDITIONS.
OTHERWISE...VFR CONDITIONS WILL PREVAIL FOR THE REMAINDER OF THE
AFTERNOON AND OVERNIGHT. HOOLEY
