ANOTHER QUIET EVENING ACROSS THE FORECAST AREA, WITH LIGHT AND
VARIABLE WINDS ACROSS INLAND AREAS WHILE EAST WINDS REMAIN ELEVATED
ACROSS THE GULF WATERS. EXPANSIVE SURFACE HIGH PRESSURE OVER THE ERN
CONUS WILL PREVAIL THROUGH THE PERIOD, WITH THE RESULTING EASTERLY
FLOW KEEPING ANY SEMBLANCE OF SIGNIFICANT MOISTURE RETURN AT BAY.
ALOFT, BROAD RIDGING OVERHEAD WILL PREVAIL IN THE SHORT TERM,
TRANSITIONING TO A NORTHWEST AND THEN NORTHERLY FLOW AS THIS RIDGE
RETROGRADES WEST AND MARKEDLY AMPLIFIES OVER THE CENTRAL CONUS
MIDWEEK, THEN DRIFTS BACK EASTWARD AGAIN OVER THE WEEKEND.
THIS PATTERN EVOLUTION WILL YIELD NO CHANCE OF RAIN THROUGH THIS
UPCOMING WEEKEND ALONG WITH A WITH A GRADUAL MODERATING TEMPERATURE
TREND. THIS WILL MOST NOTABLY BE FELT FOR AFTERNOON HIGHS WHICH
WILL CLIMB ABOVE SEASONAL NORMALS BY MID-WEEK AND PUSH INTO THE
UPPER 80S ACROSS INTERIOR SE TX AND CENTRAL LA BY THU. WITH THE
AIRMASS REMAINING DRY AND GOOD RADIATIONAL COOLING CONDITIONS
EXPECTED AT NIGHT, LOW TEMPERATURES WILL REBOUND MUCH MORE SLOWLY,
WITH BELOW NORMAL READINGS EXPECTED THROUGH THE WEEK.

ISSUED AT 1210 AM CDT MON OCT 19 2026
VFR WILL PREVAIL THROUGH THE PERIOD.
MARINE
ISSUED AT 1210 AM CDT MON OCT 19 2026
MODEST EASTERLY WINDS WILL CONTINUE ACROSS THE GULF WATERS AS AN
AREA OF HIGH PRESSURE SETTLES ACROSS THE EASTERN UNITED STATES.
THESE MODEST EAST WINDS WILL REMAIN ELEVATED THROUGH TUESDAY,
ESPECIALLY AT NIGHT, AND MAY REQUIRE HEADLINES OVER THE WATERS
BEYOND 20NM. GENERALLY LIGHT EASTERLY WINDS WILL PREVAIL FROM
WEDNESDAY THROUGH UPCOMING WEEKEND.
FIRE WEATHER
ISSUED AT 1210 AM CDT MON OCT 19 2026
HIGH PRESSURE DOMINATING THE EASTERN UNITED STATES WILL YIELD A
PREVAILING EASTERLY FLOW ACROSS THE AREA FOR THE UPCOMING WEEK,
INHIBITING SIGNIFICANT MOISTURE RETURN AND RESULTING IN NO CHANCE
OF RAIN. THIS WILL FURTHER EXACERBATE THE ONGOING DROUGHT
CONDITIONS. IN ADDITION, AN INCREASING DIURNAL TEMPERATURE RANGE
WILL CAUSE MINIMUM RELATIVE HUMIDITY VALUES TO DROP BELOW 30
PERCENT FOR MUCH OF THE UPCOMING WEEK. THE PRIMARY LIMITING FACTOR
TO MORE PRONOUNCED FIRE WEATHER DANGER WILL BE THE LACK OF WIND,
WITH EASTERLY WIND SPEEDS OF 5 TO 10 MPH EXPECTED.
