PREV DISCUSSION... /ISSUED 325 PM MDT THU JUN 28 2012/

SHORT TERM...THIS AFTERNOON THROUGH SATURDAY NIGHT...CURRENT
FORECAST INTO THIS WEEKEND APPEARS TO BE ON TRACK WITH VERY FEW
CHANGES FROM LAST NIGHT AND YESTERDAY. SHOWERS AND THUNDERSTORMS
WILL CONTINUE INTO THIS EVENING AS A SHORTWAVE TROUGH PUSHES
ACROSS THE HIGH PLAINS. SEVERE WEATHER IS NOT EXPECTED ALTHOUGH
ISOLATED WIND GUSTS AROUND 60 MPH ARE POSSIBLE DUE TO A VERY DRY
BOUNDARY LAYER. ACTIVITY WILL DISSIPATE OR PUSH EAST OF THE
FORECAST AREA BY MIDNIGHT TONIGHT WITH CLEARING SKIES.

MODELS THEN SHOW A LOW AMPLITUDE RIDGE ALOFT QUICKLY MOVING OVER
THE FORECAST AREA FOR FRIDAY. EXPECT ANOTHER HOT DAY FRIDAY
AFTERNOON WITH 700 MB TEMPERATURES INCREASING A FEW DEGREES
COMPARED TO TODAY WITH HIGHS IN THE 90S TO 103...WARMEST OVER THE
LOWER ELEVATIONS BELOW 5000 FEET. WITH LINGERING MOISTURE OVER THE
LARAMIE RANGE AND ADJACENT PLAINS NEAR THE COLORADO BORDER...CAN
NOT RULE OUT AN ISOLATED TSTORM EAST OF A LINE FROM DOUGLAS TO
LARAMIE FRIDAY EVENING.

ON SATURDAY...A WEAK SURFACE BOUNDARY AND ASSOCIATED DISTURBANCE
ALOFT WILL PUSH SOUTHEAST ACROSS THE AREA AND INTO COLORADO BY
SATURDAY EVENING. WITH PW/S INCREASING TO AROUND 1 INCH EAST OF
THE LARAMIE RANGE COMBINED WITH AMPLE LLVL INSTABILITY...AND CAPE
OVER 2500 J/KG...KEPT A CHANCE OF WIDELY SCATTERED SHOWERS AND
TSTORMS ACROSS THE HIGH PLAINS SATURDAY AFTERNOON AND EVENING.
ALTHOUGH 700MB TEMPERATURES WILL LOWER SLIGHTLY...IT WILL BE
BARELY NOTICEABLE WITH HIGHS REMAINING BETWEEN 90 TO 100 DEGREES.

LONG TERM...SUNDAY THROUGH WEDNESDAY NIGHT...
UPPER LEVEL RIDGE AXIS WILL MEANDER BETWEEN THE PLAINS AND THE
ROCKIES THIS WEEKEND INTO THE MIDDLE OF NEXT WEEK. RIDGE POSITION
SHOULD ALLOW MONSOONAL MOISTURE TO DRIFT NORTHWARD THROUGH THIS
PERIOD. STEEP DAYTIME LAPSE RATES AND MIDLEVEL MOISTURE SHOULD
ALLOW SHOWERS AND THUNDERSTORMS TO DEVELOP OFF THE HIGHER TERRAIN
MOST EVERYDAY. BEST CHANCES FOR PRECIPITATION WILL BE IN SOUTHERN
PORTIONS OF THE FORECAST AREA CLOSER TO THE MOISTURE SOURCE.
CONVECTIVE ACTIVITY WILL GENERALLY HAVE A TOUGH TIME REACHING INTO
THE PLAINS BUT THAT WILL BE LARGELY DEPENDENT ON SUBTLE SHORTWAVE
FEATURES. TEMPERATURES WILL CONTINUE TO BE ABOVE NORMAL THROUGH
THE PERIOD WITH HIGHS MAINLY IN THE 90S ACROSS SOUTHEAST WYOMING
WITH HIGHS AROUND 100 DEGREES IN THE NEBRASKA PANHANDLE.

FIRE WEATHER...MARGINAL RED FLAG CONDITIONS WILL CONTINUE OVER
SOUTHEAST WYOMING...MAINLY WEST OF THE LARAMIE RANGE. GUSTY WINDS
WILL DIMINISH THIS EVENING...BUT OVERNIGHT HUMIDITY RECOVERIES
WILL REMAIN VERY POOR ACROSS CARBON AND ALBANY COUNTIES TONIGHT
AND AGAIN ON FRIDAY NIGHT. ANOTHER DRY AND HOT DAY IS EXPECTED
FRIDAY...WITH HUMIDITIES LOWERING INTO THE SINGLE DIGITS DURING
THE DAY. WINDS APPEAR TO BE LIGHTER COMPARED TO TODAY...SO WILL
HOLD OFF ON ISSUING A FIRE WEATHER WATCH. HOWEVER...STILL EXPECT A
FEW LOCATIONS TO OBSERVE GUSTS AROUND 25 MPH DURING THE AFTERNOON
ACROSS CARBON COUNTY. OTHERWISE...THE NEXT CRITICAL DAY FOR
FIRE WEATHER APPEARS TO BE SUNDAY WITH GUSTY SOUTHWEST WINDS
POSSIBLE WEST OF THE LARAMIE RANGE.
