July 14: Mesoscale Discussion #1615
Words to know:
MLCAPE: A form of instability.
CINH: Atmospheric storm-suppressing warm air layer over the cool air.
Shear: Different directions and speeds in wind in the atmosphere layers.
MCS: Mesoscale (large area) Convective (storms) System. A large area of storms.
Low Level Jet (LLJ): A nocturnal, smaller jet stream area in lower atmosphere levels similar to the big jet stream.

Low Level Jet (LLJ): A nocturnal, smaller jet stream area in lower atmosphere levels similar to the big jet stream.
A FEW STORMS ARE DEVELOPING OVER THE HIGH TERRAIN OF N-CNTRL CO WITH COVERAGE AND INTENSITY EXPECTED TO INCREASE THROUGH THE AFTERNOON. CONVECTIVE TRENDS WILL CONTINUE TO BE MONITORED FOR A WW. STRONG INSOLATION IN COMBINATION WITH SURFACE DEWPOINTS IN THE UPPER 50S/LOWER 60S ALONG THE FOOTHILLS IS RESULTING IN MODERATELY UNSTABLE CONDITIONS /MLCAPE OF 1000 J/KG/ AND WEAKENING CINH. THE N-CNTRL CO PROFILER IS INDICATING AROUND 30 KTS OF DEEP-LAYER SHEAR...WHICH WILL BE SUFFICIENT FOR ORGANIZED STORMS POSING A THREAT OF LARGE HAIL AND DAMAGING WINDS. AS THE STORMS MOVE EWD INTO THE PLAINS...THE ENVIRONMENT APPEARS MARGINALLY FAVORABLE FOR UPSCALE GROWTH INTO AN MCS ESPECIALLY INTO SWRN NEB AS THE LOW-LEVEL JET STRENGTHENS OVERNIGHT.
July 14: Special Weather Watch (East Montana)
From The Weather Centre's Mobile StormTrack Team
The Weather Centre has issued a Special Weather Watch
for East Montana
At 2:26 PM... A warm front is pushing through Montana. This warm front will provide the instability for convection to initiate after the front moves through.
Below the front, temperatures are already into the mid 80's, while areas above the front remain in the 70's.
This watch is specifically designed to address the front moving north and not to address storms later tonight.
People outlined in this watch should keep up to date with the latest weather information.
This watch will expire around 5:00 PM. At that point, another watch will be issued for the storms themselves.
July 14 Severe Weather Discussion (Conditional Storm Action Day Declared)
A slight risk of severe weather is in effect for the North Plains into Nebraska and northeast Colorado.
A Conditional Storm Action Day has been declared today. This is because The Weather Centre believes probabilities of tornadoes, hail and winds combined are high enough that it warrants a Conditional Storm Action Day (CSAD).
