DISCUSSION
ISSUED AT 1153 AM CDT WED MAR 18 2026
THE FORECAST PERIOD WILL BE LARGELY DOMINATED BY THE RECORD-
BREAKING H5 RIDGE (~595 DAM) CURRENTLY POSITIONED OVER THE SW US.
ALTHOUGH THE RIDGE WILL SLIGHTLY SHIFT EAST AND DE-AMPLIFY LATE
THIS WEEK INTO THE UPCOMING WEEKEND, ITS INFLUENCE WILL REMAIN
STRONG OVER THE AREA, SUPPORTING DRY AND SEASONABLY WARM WEATHER.
AT THE SURFACE, SERLY FLOW WILL PREVAIL THROUGH THE FORECAST
PERIOD, AS HIGH PRESSURE REMAINS POSITIONED OVER THE GULF AND
THERMAL LOWS DEVELOP DAILY OVER THE HIGHER TERRAIN TO OUR WEST.
THE PRESENCE OF THE RIDGE AND NORTHWARD DISPLACEMENT OF THE JET
STREAM/STORM TRACK WILL KEEP ANY FRONTS NORTH OF THE AREA.
TEMPERATURES WILL WARM THROUGH THE WEEK AND INTO THE WEEKEND AS
850MB TEMPS WARM ALMOST 10 DEGREES (FROM 8 TO 18C). SERLY FLOW
WILL MAINTAIN AN E-W GRADIENT WITH HIGHS RANGING FROM THE 70S NEAR
THE IMMEDIATE COAST TO THE MID 90S OVER THE INTERIOR (WITH 20-30%
CHANCES OF TRIPLE DIGIT HIGHS OVER THE BRUSH COUNTRY BY THE
WEEKEND). FORTUNATELY RELATIVELY DRY CONDITIONS AND (AT LEAST
THROUGH FRIDAY)AND LIGHT WINDS OVERNIGHT WILL FOSTER EFFICIENT
RADIATIONAL COOLING WITH OVERNIGHT LOWS GENERALLY IN THE 50S
THROUGH THE END OF THE WEEK.

ISSUED AT 1153 AM CDT WED MAR 18 2026
GENERALLY VFR CONDITIONS WILL PREVAIL THROUGH THE TAF PERIOD.
THERE IS A LOW-MEDIUM (20-30%) CHANCE OF FOG DEVELOPMENT AT KALI
AND KVCT THURSDAY MORNING. WINDS WILL GENERALLY BE SERLY AROUND
10-15KTS THROUGH THE DAYTIME HOURS, AND THEN TREND LIGHT AND
VARIABLE OVERNIGHT.

OF PORT ARANSAS THIS WEEKEND. NO RAIN CHANCES ARE EXPECTED AT
THIS TIME.
FIRE WEATHER
ISSUED AT 1153 AM CDT WED MAR 18 2026
ALTHOUGH WINDS WILL REMAIN GENERALLY BELOW CRITICAL CRITERIA,
OCCASIONAL WIND GUSTS AROUND 20 MPH IN COMBINATION WITH RELATIVE
HUMIDITY OF 15-30% AND CRITICALLY DRY FUELS OVER THE BRUSH COUNTRY
AND INLAND COASTAL PLAINS, WILL PROMOTE ELEVATED FIRE WEATHER
CONCERNS TODAY. SIMILARLY ELEVATED CONDITIONS WILL PERSIST
THROUGH THE WEEK AND INTO THE WEEKEND WITH FIRE DANGER STATEMENTS
