.SHORT TERM...VALID FOR THU AND FRI...

MODERATE WESTERLY FLOW THIS AFTERNOON AND DECENT CAPES SHOULD LINE
UP FOR A POTENTIAL FOR THUNDERSTORM BEARING HAIL BUT STORMS WILL
BE FAIRLY CLUSTERY. THIS SHOULD KEEP MOST REPORTS NEAR SEVERE
CRITERIA AND NOT TOO MUCH OVER BUT RELATIVELY LOW WETBULB ZEROS
WILL AID THE NUMBER OF REPORTS. A MORE INTERESTING AREA IS
NORTHEAST OF BILLINGS WHERE SHEAR WILL BE DEEPER SO STORMS MAY
HAVE A BETTER CHANCE TO BE MORE DISCRETE WITH STRONGER UPDRAFTS.
CURRENTLY WESTERN HALF OF AREA IN A SEVERE WEATHER WATCH AND
SUSPECT THAT EASTERN ZONES WILL BE LATE THIS AFTERNOON. FOR
THURSDAY IT WILL BE A BIT DRIER AND WARMER IN A PREFRONTAL
COMPRESSIONAL WARMING ENVIRONMENT. SURFACE FLOW SHOULD BE MORE
WESTERLY WHICH WILL LIMIT DEWPOINT POOLING BUT RESIDUAL MOISTURE
MAY BE DEEP ENOUGH FOR ISOLATED AFTERNOON CONVECTION. LOBE OF THE
HUDSON BAY LOW ROTATES THROUGH SASKATCHEWAN THURSDAY NIGHT AND
THIS DRIVES A FRONT THROUGH THE AREA LEAVING A COOL AIRMASS AND
UPSLOPE CONDITIONS FOR FRIDAY. THIS WILL ALLOW FOR SCATTERED
SHOWER ACTIVITY BUT MORE SIGNIFICANTLY CLOUD COVER WILL SUPPRESS
INSOLATION AND COOL SURFACE AIRMASS WILL SUPPORT WELL BELOW NORMAL
TEMPERATURES. BORSUM.

.LONG TERM...VALID FOR SAT...SUN...MON...TUE...WED...

UNSEASONABLY COLD AIR WILL HANG ON SATURDAY. 12Z GFS MUCH
STRONGER/COLDER THAN THE NAM WITH SECONDARY WAVE AS IT COMES
THROUGH NORTHWEST FLOW ALOFT EARLY SATURDAY. WITH SUCH HIGH
AMPLITUDE FLOW (AND UPSLOPE AT LOW LEVELS) SEE ON REASON WHY WE
SHOULD BEGIN TO MODERATE AS THE NAM SUGGESTS...SO HAVE SIDED WITH
THE COOLER GFS. WE MAY STRUGGLE TO CLIMB THROUGH THE 60S...AND
WITH SUFFICIENT CLOUD COVER THE BILLINGS RECORD COOL HIGH OF 63F
MAY BE IN JEOPARDY. FOR NOW HAVE TWEAKED TEMPS DOWN A TAD...AND
WOULD EXPECT HIGHS GENERALLY IN THE MID 60S TO NEAR 70...WHICH IS
STILL A GOOD 15-20 DEGREES BELOW NORMAL. WILL ALSO SUSTAIN LOW
CHANCE POPS ON SATURDAY AS THE WAVE COMES THROUGH.

MODERATION BEGINS SUNDAY AS FLOW ALOFT BACKS AND HEIGHTS BEGIN TO
RISE. WARM-UP LOOKS TO BE GRADUAL THOUGH (BLOCK REMAINS IN THE
EASTERN PACIFIC)...AND WOULD EXPECT HIGHS TO STAY BELOW NORMAL
UNTIL AT LEAST TUESDAY. WILL KEEP LOW POPS EVERYWHERE SUNDAY
AFTN/EVNG AND IN THE SOUTH MONDAY WITH TRICKY NORTHWEST FLOW (A
WEAK WAVE IS FCST BY MODELS ON SUNDAY)...BUT SHOULD NOT AMOUNT TO
MUCH DURING THIS TIME AS THE AIRMASS LOOKS TO BE FAIRLY DRY AND
STABLE. EVEN LOW CHANCE POPS MAY BE OVERDONE DURING THIS TIME.

MODELS DIVERGE LATE IN THE EXTENDED WITH REGARD TO HOW QUICKLY WE
RETURN TO SOUTHWEST FLOW...BUT CONSENSUS IS TO DO THIS BY MIDWEEK
AS TROFFING OCCURS ALONG THE PACIFIC COAST. NEAR NORMAL TEMPS WITH
AN INCREASING CHANCE OF TSTMS ACROSS THE AREA LOOKS GOOD FOR
WEDNESDAY. IF STRONG RIDGING/SOUTHWEST FLOW DOES DEVELOP THEN
WOULD EXPECT HIGHS TO RETURN INTO THE 90S (GIVEN IT IS STILL MID
AUGUST)...BUT WITH UNCERTAINTY WILL BE CONSERVATIVE WITH TEMPS FOR
NOW.

OVERNIGHT TONIGHT.
