LEE SURFACE TROUGH WILL DEEPEN OVER THE CNTRL AND NRN HIGH
PLAINS...PARTLY IN RESPONSE TO A WEAK EMBEDDED UPPER SHORTWAVE
TROUGH MOVING INTO THE NRN ROCKIES. THIS WILL RESULT IN WARM...GUSTY
S WINDS OVER THE CNTRL AND NRN PLAINS.
...SERN STATES...
HIGH PRESSURE WILL SETTLE ACROSS THE LOWER MS VALLEY AND GULF COAST
REGION...WITH DECREASING WINDS...COOL TEMPERATURES AND LOW HUMIDITY.
AFTER A VERY COOL MORNING...TEMPERATURES WILL RISE INTO THE 60S F
WITH MIN RH IN THE 20 PERCENT RANGE. WLY WINDS NEAR 10 MPH ARE
LIKELY WITH A FEW HIGHER GUSTS...BUT OVERALL SPEEDS WILL BE MUCH
LESS THAN YESTERDAY.
...CNTRL AND NRN HIGH PLAINS...
A WEAK UPPER TROUGH WILL HELP BREAK DOWN THE UPPER RIDGE WITH A
DEEPENING LEE TROUGH AT THE SURFACE. BEHIND THIS TROUGH...WLY WINDS
OF 15-20 MPH ARE EXPECTED...WHILE SLY WINDS OF 15-20 MPH OCCUR E OF
THE TROUGH ACROSS THE WRN DAKOTAS AND WRN NEB. ALTHOUGH WINDS WILL
BE A BIT MARGINAL FOR A CRITICAL THREAT...RH WILL BE QUITE LOW FROM
