Area forecast discussion, Jun 19, 4:03 PM MST, 1 hour 17 minutes before

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE BILLINGS MT
503 PM MDT MON JUN 19 2006

.SHORT TERM...VALID FOR TUE AND WED...

...UPDATED TO INCLUDED SEVERE THUNDERSTORM WATCH HEADLINE...

FORECAST STILL ON TRACK FOR A SHOT OF SHOWERS AND THUNDERSTORMS
THIS EVENING AS COLD FRONT PUSHES ACROSS THE AREA FROM WEST TO
EAST. PATTERN SETTLES DOWN AFTER THIS WITH A FEW MILD DAYS
TEMPERATURE WISE...WITH WINDY CONDITIONS TUESDAY.

TONIGHT...SOUTHEAST LOW LEVEL FLOW HAS BROUGHT DEWPOINTS UP A BIT
TODAY FROM SHERIDAN EASTWARD TO NORTH DAKOTA BORDER...BUT ONLY
INTO LOWER 40S AT THIS TIME. THESE MAY RISE INTO MID TO UPPER 40S
BY LATE AFTERNOON AND EARLY EVENING. EXPECTED 500 MB 50 KNOT JET
LOOKS TO BE PUSHING INTO SOUTHERN ZONES LATER THIS AFTERNOON AS
WELL...THIS IS A BIT FURTHER SOUTH AND EAST THAN EXPECTED
YESTERDAY. INSTABILITY DOESNT LOOK TO BE ALL THAT HIGH THIS
EVENING WITH THE FRONT AND UPPER WAVE...BUT COMBINATION OF STRONG
SHEER OF AROUND 50 KNOTS FROM SURFACE TO 6 KM AND LIMITED CAPE
SHOULD STILL BE ENOUGH TO GET A FEW SEVERE STORMS IN EASTERN
ZONES...MORE THAN LIKELY FAR SOUTHEAST ZONES. WILL CONTINUE TO
MENTION STRONG WINDS WITH THUNDERSTORMS IN WEST AND CENTRAL ZONES
WITH MORE ELEVATED NATURE TO STORMS.

TUESDAY...A FASTER WESTERLY FLOW TO BE OVER THE AREA. LOOKING MORE
AND MORE LIKE A DRY DAY. MODEL SOUNDINGS TRENDING TO WARMER AIR AT
MID LEVELS RESULTING IN LESS INSTABILITY. AIRMASS WILL BE VERY
DRY. WITH ALL THIS...HAVE REMOVED CHANCE OF WEATHER FROM THE
GRIDS. AIRMASS WILL BE WELL MIXED WITH LINKED WESTERLY FLOW WHICH
WILL RESULT IN WINDY CONDITIONS AND HAVE PUT IN 20 TO 35 MPH ACROSS
MOST OF THE AREA.

WEDNESDAY...UPPER PATTERN A LITTLE MESSY WITH A WEAKER WEST
NORTHWEST FLOW OVER THE AREA. SOME WEAK CYCLONIC FLOW PROGGED BY
GFS IN EASTERN ZONES AND LESS TO THE WEST. HAVE KEPT PREVIOUS POPS
IN EAST AND EXPANDED A BIT TO THE WEST. OTHERWISE HAVE KEPT
FORECAST DRY AND A BIT COOLER FROM TUESDAY. RASCH

.LONG TERM...VALID FOR THU...FRI...SAT...SUN...MON...

MODELS REMAIN FAIRLY CONSISTENT WITH EACH OTHER AND RUN TO
RUN. ZONAL FLOW WILL PREVAIL THROUGH THE FIRST HALF OF THE
EXTENDED...WITH RIDGING FOR THE SECOND HALF.  MAIN UNCERTAINTY
EXISTS WITH THE POSSIBLE PASSAGE OF A SHORT WAVE FRI INTO FRIDAY
NIGHT. THIS MAY AMPLIFY THE FLOW ENOUGH TO BUILD A WEAK SURFACE
HIGH INTO THE AREA SATURDAY FOR A SLIGHTLY COOLER DAY. CHANCES OF
PRECIPITATION WITH THAT FEATURE LOOK PRETTY MINIMAL AS THE MAIN
ENERGY IS TO THE NORTH...BUT DID INTRODUCE SLIGHT CHANCE NEAR
BAKER. AFTER SATURDAY...THE MAIN UNCERTAINTY IS IN THE AMPLITUDE
OF THE RIDGE AND EXACTLY WHERE THE RIDGE AXIS WILL RESIDE. THE
LATEST GFS IS MORE AMPLIFIED THAN PREVIOUS RUNS...BUT STILL KEEPS
THE AXIS JUST TO THE WEST. WITH THAT IN MIND THE MAIN THERMAL
RIDGE WILL BE TO THE WEST WITH SOME EASTERLY GRADIENT TO KEEP FROM
GETTING TOO WARM. SO EVEN IF THE RIDGE AXIS DOES END UP BEING
FLATTER...IT DOES NOT APPEAR IT WILL HAVE MUCH IMPACT ON
TEMPERATURES ASSUMING THE AXIS POSITION IS CORRECT. MOORE

&&

.AVIATION...

HIGH BASED THUNDERSTORMS...WITH MAINLY VFR CONDITIONS...WILL EXIT
THE WESTERN AREA THIS EVENING AND SPREAD EAST TO MLS AND BHK LATE
THIS EVENING. THE STORMS WILL BECOME FAIRLY WIDESPREAD EAST OF A
BIL TO SHR LINE AFTER 00Z. MVRF CONDITIONS ALONG WITH STRONG WIND
GUSTS AND SMALL HAIL WILL BE POSSIBLE WITH THE STRONGER STORMS.
THE STORMS WILL EXIT EASTERN AREAS BY 09Z WITH CLEARING SKIES BY
09Z. BREEZY...DRY CONDITIONS ARE EXPECTED ON TUESDAY.  MOORE
