DISCUSSION
(TODAY THROUGH SATURDAY)
ISSUED AT 1223 AM CDT SUN OCT 18 2026
QUIET EVENING, AS EXPECTED, ACROSS THE FORECAST AREA, WITH GUSTY
NORTH WINDS SUBSIDING INLAND ON SCHEDULE AND PERHAPS A LITTLE AHEAD
OF SCHEDULE OVER THE COASTAL WATERS. NOT TOO MUCH TO WRITE ABOUT FOR
THIS FORECAST, AS SURFACE HIGH PRESSURE CENTERED 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 HIGH 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 90 ACROSS
INTERIOR SE TX AND CENTRAL LA BY FRIDAY. 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.
AVIATION
(06Z TAFS)
ISSUED AT 1223 AM CDT SUN OCT 18 2026
VFR WILL PREVAIL THROUGH THE PERIOD.
MARINE
ISSUED AT 1223 AM CDT SUN OCT 18 2026
NORTHEAST WINDS WILL CONTINUE TO GRADUALLY EASE TONIGHT AND BECOME
MORE MODEST FROM THE EAST ON SUNDAY 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 TEMPERATURE THROUGH THE
END OF THE WEEK.
FIRE WEATHER
ISSUED AT 1223 AM CDT SUN OCT 18 2026
HIGH PRESSURE DOMINATING THE EASTERN UNITED STATES WILL YIELD A
PREVAILING EASTERLY FLOW ACROSS THE AREA FOR THE UPCOMING WEEK,
INHIBITING 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 PRONOUNCED FIRE WEATHER DANGER
WILL BE THE LACK OF WIND, WITH EASTERLY WIND SPEEDS OF 5 TO 10 MPH
EXPECTED.
