DISCUSSION
ISSUED AT 206 AM CDT TUE JUL 14 2026
A VERY STRONG ELONGATED UPPER RIDGE HAS BROUGHT ALL-TIME RECORD
HIGHS TO SEVERAL SITES IN THE MOUNTAIN WEST. HIGH PRESSURE OVER
THE MIDDLE OF THE COUNTRY WILL STEER THE WORST OF THE HEAT
ACROSS THE NORTHERN PLAINS TO THE GREAT LAKES. A STALLED OUT LOW
PRESSURE DISTURBANCE OVER ALABAMA, WITH A WEST-EAST STATIONARY
BOUNDARY IN THE DEEP SOUTH WILL LARGELY KEEP PRECIPITATION TO
OUR SOUTH THROUGH MIDWEEK. ONLY A SLIGHT CHANCE OF
SHOWERS/STORMS COVERS SOUTHERNMOST PORTIONS OF THE QUAD STATE
THIS AFTERNOON, WITH LIMITED MODEL SUPPORT.
THE DEEP SOUTH LOW DRIFTS NORTHWESTWARD TOWARDS THE MID-SOUTH
TOMORROW. NORTH OF THIS DISTURBANCE, WINDS THROUGH THE QUAD
STATE WEDNESDAY WILL BE EASTERLY. PRECIP CHANCES INCREASE, WITH
SEMO FAVORED ACROSS A MAJORITY OF MODELS. PRIMARILY DIURNALLY
DRIVEN, WITH DECENT CAPE BUT TRIVIAL SHEAR, PULSE STORMS WILL
YIELD VERY LITTLE STRONG TO SEVERE WEATHER POTENTIAL. PWS OF
2.2IN WILL YIELD HEAVY RAIN RATES BUT TRAINING IS LIMITED.
SLOW CONTINUED DRIFTING OF THE DISTURBANCE WILL YIELD DIURNAL
CHANCES OF SHOWERS/STORMS THURSDAY AND FRIDAY AS WELL, WITH
FRIDAY FAVORING THE NORTHEAST AS THE SYSTEM MOVES TOWARDS THE
OHIO RIVER VALLEY. WEAKENING OF THE RIDGE IN THE EAST MAY
BOLSTER PRECIP CHANCES WITH A WEAK SHORTWAVE DISTURBANCE FRIDAY
NIGHT INTO EARLY SATURDAY. AT THIS TIME, SOME OF THE WARMEST
CONDITIONS ARE PROJECTED TO OCCUR OVER THE WEEKEND WITH HIGHS IN
THE LOWER 90S. HEATRISK MAXES OUT FRIDAY-SATURDAY IN MODERATE
(LEVEL 2). A SYSTEM MOVING THROUGH THE GREAT LAKES EARLY NEXT
WEEK COULD BRING A COLD FRONT INTO THE QUAD STATE, THOUGH MODELS
VARY ON POSITIONING.
