MESOSCALE DISCUSSION 1422
NWS STORM PREDICTION CENTER NORMAN OK
0242 PM CDT WED JUL 01 2026
AREAS AFFECTED...PORTIONS OF IDAHO AND MONTANA
CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY
VALID 011942Z - 012145Z
PROBABILITY OF WATCH ISSUANCE...5 PERCENT
SUMMARY...ISOLATED STRONG TO SEVERE WIND GUSTS WILL BE POSSIBLE AS
THUNDERSTORMS OVERSPREAD PORTIONS OF NORTHEAST IDAHO AND
SOUTHWEST/CENTRAL MONTANA. WATCH ISSUANCE IS NOT EXPECTED.
DISCUSSION...LIGHTNING COUNTS HAVE BEEN TRENDING UP ACROSS NORTHEAST
ID AND SOUTHWEST MT OVER THE PAST HOUR AS AN UPPER WAVE BEGINS TO
SHIFT EAST AND TEMPERATURES WARM INTO THE UPPER 60S/LOW 70S. A
COMBINATION A MODEST LOW-LEVEL MOISTURE AND COLD TEMPERATURES ALOFT
ARE SUPPORTING MLCAPE VALUES ON THE ORDER OF 500 J/KG, WHICH MAY
INCREASE SLIGHTLY THROUGH LATE AFTERNOON AS DAYTIME HEATING AND SOME
DEGREE OF MID-LEVEL ASCENT/COOLING CONTINUES. DOWNSTREAM OF THE
DEVELOPING CONVECTION, LOW-LEVEL LAPSE RATES HAVE STEADILY INCREASED
TO AROUND 8 C/KM, WHICH SHOULD SUPPORT SOME POTENTIAL FOR
ACCELERATING DOWNDRAFTS AND STRONG/SEVERE DOWNBURST WINDS.
ADDITIONALLY, 25-30 KNOT MID-LEVEL FLOW SAMPLED BY THE KSFX VWP
SUGGESTS THAT SOME DEGREE OF CELL ORGANIZATION IS POSSIBLE AND MAY
SUPPORT A TRANSIENT THREAT FOR LARGE HAIL AS WELL AS SEVERE GUSTS.
IN GENERAL, THIS POTENTIAL SHOULD REMAIN SUFFICIENTLY ISOLATED TO
PRECLUDE WATCH ISSUANCE.
