DAY 4-8 CONVECTIVE OUTLOOK

..DISCUSSION
RELATIVELY LITTLE CHANGE IS EXPECTED IN THE UPPER-LEVEL PATTERN FROM
MID TO LATE THIS WEEK. A BROAD TROUGH IN THE WEST WILL BRING
SOUTHWESTERLY FLOW ACROSS THE ROCKIES AND PARTS OF THE PLAINS. IN
THE EAST, AN UPPER RIDGE WILL PERSIST. DURING THE WEEKEND, MODELS
ARE IN GENERAL AGREEMENT THAT THE UPPER RIDGE WILL FLATTEN AND
BROADEN ACROSS THE SOUTHERN U.S. THIS PATTERN WILL FAVOR THE
MAINTENANCE OF A VERY MOIST AIRMASS WITHIN PARTS OF THE PLAINS INTO
THE MIDWEST AND SOUTHEAST. THE LACK OF MORE NOTABLE MID-LEVEL AND
SURFACE FEATURES DECREASE PREDICTABILITY WITH REGARD TO WHERE SEVERE
CONVECTION MAY OCCUR. THAT BEING SAID, SUBTLE SURFACE
BOUNDARIES/SHORTWAVE TROUGHS MAY PROMOTE CONVECTIVE DEVELOPMENT EACH
DAY WITHIN PARTS OF THE PLAINS/MIDWEST. TRENDS IN MODEL GUIDANCE
WILL CONTINUE TO BE MONITORED, BUT CONFIDENCE REMAINS LOW IN PLACING
SEVERE PROBABILITIES.
