AVIATION...
SCATTERED THUNDERSTORMS ACROSS THE AREA SHOULD DISSIPATE SHORTLY
AFTER SUNSET WITH THE LOSS OF DAYTIME HEATING. NEXT CONCERN IS
STRONG UPPER LOW MOVING IN FROM THE SOUTHWEST LATE TONIGHT. WITH
SOME INSTABILITY AND STRONG FORCING FOR ASCENT EXPECT THAT
CONVECTION WILL DEVELOP IN THE JAMES AFTER MIDNIGHT AND THEN SPREAD
TOWARD I-29 TOWARD DAWN. CIGS WILL START OFF VFR BUT AS
PRECIPITATION PERSISTS EXPECTS CIGS TO FALL BELOW 3000 FT IN KHON
LATE TONIGHT AND THEN BY FRI MORNING IN KSUX AND KFSD.  RAIN
EXPECTED TO CONTINUE INTO THE AFTERNOON AT KSUX AND KFSD BUT SHOULD
END AT KHON. FOR KSUX AND KFSD...THIS WILL MEAN A PERIOD WHERE CIGS
MAY FALL BLO 1000 FT AT TIMES WITH VSBYS BLO 3SM IN HEAVIER RAIN.
AT KHON...EXPECT A SLOW IMPROVEMENT IN CIGS DURING THE AFTERNOON BUT
KEPT CIGS AT 3000 FT AS THERE WILL BE A LOT OF LOW LEVEL MOISTURE SO
THAT ANY BREAKS SHOULD RESULT IN REFORMATION OF BKN CU DURING THE
AFTERNOON.

.PREV DISCUSSION...
FIRST S/W EJECTING NEWD INTO CWA BEGINNING TO TRIGGER SCT TRW ACRS
WRN CWA AS OF 20Z. THESE SHUD CONT INTO THE EVE WITH POT FOR A FEW
SVR STORMS. STORMS SHUD DISSIPATE ERN CWA THIS EVE AS STORMS LOSE
HEATING. HWVR...STORMS SHUD CONT TO FIRE UP WRN CWA CLOSER TO UPPER
LOW AND SFC FNT. THIS BNDRY WL SHIFT EWD DURING THE NIGHT AND AS LLJ
INCREASES...WUD EXPECT TRW TO BECOME MORE WDSPRD NR FNT DURING THE
NIGHT WITH BEST CHC W OF I29 AFT 06Z. SO WL GO WITH HIGHEST POPS
ACRS THE W. WL NEED TO WATCH FOR PSBL HEAVY RAINS ESPEC IF IT OCCURS
IN JAMES RVR VALLEY.

CONTINUING TO DEAL WITH THE STUBBORN UPPER LEVEL LOW OVER THE NEXT
FEW DAYS AS IT BEGINS TO MOVE EAST. EXPECT FRIDAY TO BE WETTEST OF
THE BUNCH AS MAIN SHORT WAVE CURRENTLY IN EASTERN MONTANA ROTATES
AROUND AND INTO CWA. SHORTWAVE ROTATES TO THE NORTH ON FRIDAY
EVENING...BUT WILL LIKELY KEEP SOME SHOWERS AROUND ESPECIALLY ACROSS
THE NORTHERN HALF OF THE CWA NEAR THE CENTER OF THE LOW. AS UPPER
LOW SHIFTS TO THE EAST...EXPECT A FEW DAYS OF INSTABILITY DRIVEN
SHOWERS AND THUNDERSTORMS.  WITH THE UPPER LOW NEAR BY ON
SATURDAY...COULD SEE A FEW AFTERNOON COLD CORE FUNNELS GIVEN
SUFFICIENT DESTABILIZATION.

UPPER LEVEL LOW EVENTUALLY SHIFTS EAST AND COMBINES FORCES WITH A
WAVE OVER THE HUDSON BAY.  RIDGE OF HIGH PRESSURE BUILDS INTO THE
REGION RESULTING IN DRY CONDITIONS AND LIGHT WINDS...SOMETHING THAT
HAS BEEN EXTREMELY UNCOMMON THIS SPRING.

HOWEVER...THE TRANQUIL CONDITIONS DON/T LOOK TO PERSIST AS A TROUGH
WORKS INTO THE NORTHERN PLAINS. THE GFS IS MORE PROGRESSIVE THAN THE
ECMWF WITH THIS SYSTEM. HAVE SIDED WITH THE SLOWER SOLUTION...GIVEN
THE GFS MOVES THE SYSTEM TO THE EAST DESPITE THE UPPER LEVEL JET
REMAINING ON THE BACKSIDE OF THE TROUGH. IN ADDITION...THE MID AND
UPPER LEVEL FORCING HANGS BACK TO THE WEST...SUGGESTING THE GREATEST
PRECIP POTENTIAL WOULD BE LATE ON THURSDAY OR LATER.  CONVECTION
POTENTIAL WILL LIKELY DEPEND ON CAP STRENGTH...WITH FAIRLY WARM AIR
AHEAD OF THE FRONT.
