DISCUSSION
ISSUED AT 156 PM CDT TUE JUL 7 2026
..SYNOPSIS
ENSEMBLES ARE IN GOOD AGREEMENT WITH THE LARGE SCALE PATTERN
OVER THE NEXT 7 DAYS, DEPICTING THE CURRENT ZONAL FLOW TO
TRANSITION INTO A SORT OF OMEGA BLOCK PATTERN WITH RIDGING
ACROSS THE CENTRAL CONUS. DETAILS LESS CERTAIN OF COURSE.
..SEVERE AND FLASH FLOOD POTENTIAL
WATER VAPOR IMAGERY INDICATES AN UPPER LEVEL TROUGH ACROSS
MONTANA SLOWLY PROPAGATING EASTWARD. AS THIS FEATURE CONTINUE TO
PROPAGATE EASTWARD THIS EVENING, ANTICIPATE A STRONG 850MB JET
TO DEVELOP WITH NOSE OF THIS FEATURE INTO THE SOUTHERN RED RIVER
VALLEY. CURRENTLY, SHOWERS ARE DEVELOPING ALONG A 700MB BOUNDARY
ACROSS CENTRAL NORTH DAKOTA, WITH ADDITIONAL ACTIVITY ASSOCIATED
WITH AN MCV ACROSS THE SOUTHERN RRV AND WEST CENTRAL MINNESOTA.
THIS ACTIVITY WILL CONTINUE EASTWARD, ALTHOUGH IMPACTS WILL BE
MINIMAL. LATER THIS EVENING, THE 850MB FRONT WILL SHIFT NORTH AS
THE LOW LEVEL JET INCREASES. SURFACE INSTABILITY WILL REMAIN
ACROSS SOUTH DAKOTA, BUT WITH INSTABILITY ALONG THE ELEVATED
FRONT AND STRONGER WARM AIR ADVECTION THERE IS A VERY HIGH
CHANCE FOR ELEVATED THUNDERSTORMS ALONG AND SOUTH OF I-94/HWY10.
SEVERE POTENTIAL...FREEZING LEVELS ARE NEAR 15 KFT, BUT GIVEN
THE ELEVATED NATURE OF THE STORMS POTENTIAL EXISTS FOR NEAR
SEVERE TO SEVERE HAIL GIVEN MUCAPE NEAR 2000 J/KG AND EFFECTIVE
SHEAR NEAR 50 KNOTS. POTENTIAL ALSO EXISTS FOR SEVERE WIND GIVEN
THE ANTICIPATED STRONG LOW LEVEL BULK SHEAR, EVEN WITH THE
STORM BEING ELEVATED. THE ELEVATED NATURE OF THE STORMS WILL
LIMIT SEVERE POTENTIAL, BUT WILL NOT ELIMINATE SEVERE POTENTIAL.
EXCESSIVE RAINFALL/FLASH FLOOD POTENTIAL...ANTICIPATE HEAVY
RAINFALL RATES GIVEN PWATS NEAR 1.75 INCHES ALONG WITH SOUNDINGS
INDICATING EFFICIENT RAINFALL RATE PROCESSES (PLUS HIGH FREEZING
LEVEL). GIVEN THE WEST TO EAST POSITION OF THE ELEVATED FRONT,
POTENTIAL ALSO EXISTS FOR TRAINING STORMS. CAM GUIDANCE
INDICATING MEAN RAINFALL 1-2 INCHES WITH MAX RAINFALL NEAR 5
INCHES. GIVEN ALL OF THIS, PLUS THE RAIN THAT FELL YESTERDAY
(1-2 INCHES) ACROSS WEST CENTRAL MINNESOTA, WILL ISSUE A FLOOD
WATCH FOR FLASH FLOOD POTENTIAL (10P-7A).
..DANGEROUS HEAT
AS THE RIDGING BUILDS INTO THE WEEKEND, ANTICIPATE MAX
TEMPERATURES 95F-100F (MAYBE A BIT WARMER) ACROSS MUCH OF THE
REGION SATURDAY THROUGH MONDAY. HEAT RISK, WET BULB GLOBE TEMP,
AND HEAT INDEX VALUES ALL INDICATE A DANGEROUS HEAT EPISODE.
