MESOSCALE DISCUSSION 0373
NWS STORM PREDICTION CENTER NORMAN OK
0225 PM CDT FRI APR 10 2026
AREAS AFFECTED...PORTIONS OF WESTERN...CENTRAL...AND NORTHERN NEVADA
INTO EXTREME SOUTHEAST OREGON AND EXTREME SOUTHWEST IDAHO
CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY
VALID 101925Z - 102130Z
PROBABILITY OF WATCH ISSUANCE...20 PERCENT
SUMMARY...A FEW INSTANCES OF SEVERE HAIL OR WIND MAY ACCOMPANY THE
STRONGER STORMS THIS AFTERNOON.
DISCUSSION...MRMS MOSAIC RADAR DATA SHOW CONVECTIVE CORES DEEPENING
TO THE LEE OF THE SIERRA OVER PORTIONS OF WESTERN NV, WITH
CONVECTIVE INITIATION UNDERWAY ACROSS CENTRAL NV. DIURNAL HEATING
HAS HELPED BOOST SURFACE TEMPERATURES INTO THE LOW 60S F, BENEATH 8+
C/KM MID-LEVEL LAPSE RATES, YIELDING MLCAPE OVER 500 J/KG (PER 19Z
MESOANALYSIS). BUOYANCY SHOULD ONLY INCREASE THROUGH THE AFTERNOON
WITH CONTINUED HEATING, RESULTING IN INCREASED STORM COVERAGE AND
INTENSITY. WHILE TROPOSPHERIC FLOW WILL REMAIN GENERALLY
UNIDIRECTIONAL, VERTICAL SPEED SHEAR WILL SUPPORT ORGANIZED
MULTICELLS AND TRANSIENT SUPERCELLS AS THE PRIMARY MODES OF
CONVECTION. ELONGATED, STRAIGHT HODOGRAPHS SUGGEST THAT SEVERE HAIL
WILL BE THE MAIN THREAT, THOUGH A COUPLE OF SEVERE GUSTS ARE ALSO
POSSIBLE. THE OVERALL SEVERE THREAT SHOULD REMAIN ISOLATED THOUGH,
SO A WW ISSUANCE IS NOT CURRENTLY ANTICIPATED.
