..SYNOPSIS
BETWEEN A LARGE-SCALE TROUGH ENCOMPASSING THE EASTERN TWO-THIRDS OF
THE CONUS AND AN UPPER RIDGE OVER THE WEST, A ROBUST MIDLEVEL SPEED
MAX WILL OVERSPREAD THE NORTHERN/CENTRAL PLAINS DURING THE DAY. AT
THE SAME TIME, A RELATED COLD FRONT WILL ADVANCE SOUTHEASTWARD
ACROSS THE REGION.
ALONG/BEHIND THE COLD FRONT/SURFACE TROUGH, AMPLE DIURNAL HEATING
WILL RESULT IN A WELL-MIXED BOUNDARY LAYER, WITH 15-20 PERCENT RH
EXPECTED ACROSS PARTS OF EASTERN WY INTO THE NE PANHANDLE AND
VICINITY. HERE, ENHANCED LOW/MIDLEVEL FLOW ALONG THE PERIPHERY OF
THE PASSING SPEED MAX AND A TIGHTENING PRESSURE GRADIENT WILL RESULT
IN 15-25 MPH SUSTAINED NORTHWESTERLY SURFACE WINDS. THESE DRY/BREEZY
CONDITIONS ATOP DRY/RECEPTIVE FUELS WILL YIELD ELEVATED TO LOCALLY
CRITICAL FIRE-WEATHER CONDITIONS DURING THE AFTERNOON.
DESPITE RELATIVELY WEAKER UPPER-LEVEL SUPPORT, STRONG TERRAIN-DRIVEN
WINDS OF 15-20 MPH (LOCALLY GREATER IN GAP-FLOW AREAS AND HIGHER
ELEVATIONS) AND 10-15 PERCENT RH WILL PROMOTE LOCALLY ELEVATED FIRE
WEATHER CONDITIONS ACROSS PARTS OF THE EASTERN GREAT BASIN, FOUR
CORNERS, AND CENTRAL ROCKIES. HOWEVER, THESE CONDITIONS APPEAR TOO
LOCALIZED FOR HIGHLIGHTS AT THIS TIME.
