SHORT TERM
(TONIGHT THROUGH SATURDAY NIGHT)
ISSUED AT 922 PM CDT THU MAR 19 2026
CURRENT CONDITIONS IN THE UPPER LEVELS HAVE A STRONG DOME OF HIGH
PRESSURE OVER SOUTHERN CALIFORNIA, ARIZONA, AND NORTHWEST MEXICO
WHICH IS ANCHORING A BROAD HIGH RIDGE OVER THE ENTIRE WESTERN
CONUS. THE TROUGH THAT BROUGHT US THE COLD WEATHER A COUPLE NIGHTS
AGO HAS MOVED EAST AND ITS AXIS IS JUST OFF THE EAST COAST. AT THE
SURFACE, HIGH PRESSURE IS CENTERED OVER THE NORTHERN GULF. THIS
EVENING'S BALLOON SOUNDING SHOWS A GENERALLY DRY COLUMN OF AIR,
ALTHOUGH THE 0.6" PW IS A TENTH HIGHER THAN THIS MORNING. THE
SLIGHTLY MOISTER AIR IS INDICATIVE OF THE LOW LEVEL HIGH PRESSURE
MOVING EASTWARD AND BEGINNING TO SPIN SOME MOISTURE OUT OF THE
GULF AND INTO OUR ENVIRONMENT. HOWEVER, THE DOMINATION OF UPPER
LEVEL HIGH PRESSURE IS KEEPING US WARM AND DRY FOR THE EXTENT OF
THIS SHORT TERM PERIOD. TEMPERATURES TONIGHT WILL BE AROUND THE
SEASONAL NORMALS OF OVERNIGHT LOWS BETWEEN 50-55 BUT WILL WARM
TOMORROW TO 8-10 DEGREES ABOVE NORMAL DAYTIME HIGHS IN THE LOW
70S. AGAIN, THIS PATTERN WILL HOLD THROUGH THE WEEKEND.
LONG TERM
(SUNDAY NIGHT THROUGH THURSDAY NIGHT)
ISSUED AT 922 PM CDT THU MAR 19 2026
BY THE EXTENDED PERIOD THE RIDGE AND TROUGH DOMINATING CONDITIONS
NOW THROUGH WEEKEND WILL BREAK DOWN AND BECOME SHALLOWER, LOSING
SOME OF THEIR STRENGTH AND BECOMING A BIT ZONAL. HOWEVER, THE
SAME GENERAL PLACEMENT WILL REMAIN LEAVING US WITH MUCH THE SAME
CONDITIONS AS THE SHORT TERM. NO RAIN AND ABOVE NORMAL
TEMPERATURES WILL CONTINUE TO BE THE STORY.
