NEAR TERM
(TODAY)
ISSUED AT 259 AM CDT FRI APR 10 2026
AS SFC HIGH PRESSURE CONTINUES TO DOMINATE THE SOUTHEASTERN U.S.,
DRY CONDITIONS REMAIN IN PLACE. UNDER MOSTLY SUNNY SKIES, HIGH
TEMPERATURES ARE FORECAST TO REACH THE UPPER 70S TO LOWER 80S
THROUGH THE TN VALLEY THIS AFTERNOON. WINDS WILL REMAIN LIGHT AND
MOSTLY SOUTHERLY IN DIRECTION, ADVECTING MOISTURE INTO THE TN
VALLEY AND DECREASING THE OVERALL FIRE RISK AS RH VALUES REMAIN IN
THE 30-40% RANGE. HOWEVER, DRY FUELS CONTINUE TO URGE INCREASED
AWARENESS AND CAUTION.
SHORT TERM
(FRIDAY NIGHT THROUGH SUNDAY)
ISSUED AT 831 PM CDT THU APR 9 2026
HEADING INTO THE WEEKEND, THE AFOREMENTIONED SFC HIGH DRIFTS A BIT
TO THE SOUTHWEST BECOMING MORE CENTERED ACROSS THE SOUTHEAST. THE
TENNESSEE VALLEY REMAINS SITUATED INBETWEEN RIDGING OVER THE
PLAINS AND TROUGHING IN THE NORTHEAST. AS A RESULT, THE DRY
WEATHER PATTERN CONTINUES THROUGH THE END OF WEEKEND. EXPECT A
CONTINUED WARMING PATTERN AS SOUTHERLY FLOW WILL BRING BOTH WARM
AND MOIST AIR NORTHWARD INTO THE LOCAL FORECAST AREA. TEMPERATURES
ON SATURDAY AND SUNDAY RISE INTO THE LOW TO MID 80S WITH MORNING
LOWS IN THE MID TO UPPER 50S. DEWPOINTS ONLY IN THE LOW 50S SHOULD
KEEP HEAT INDEX VALUES ESSENTIALLY THE SAME AS THE AIR
TEMPERATURES.
LONG TERM
(SUNDAY NIGHT THROUGH THURSDAY)
ISSUED AT 831 PM CDT THU APR 9 2026
BY THE START OF THE WORK WEEK WE WILL BE IN A SOLID BLOCKING PATTERN
BOTH AT THE SURFACE AND ALOFT. ALOFT, A TROUGHING WEST/RIDGING EAST
PATTERN WILL DOMINATE THROUGH THE PERIOD. AT THE SURFACE, STRONG HIGH
PRESSURE TO OUR EAST WILL PROMOTE CONTINUAL SSE FLOW. THIS WILL KEEP
TEMPS IN THE MID 80S WITH DEW POINTS IN THE 50S THROUGH THE WORK
WEEK. OUR ATTENTION WILL THUS BE DIRECTED TOWARDS WHEN THE BLOCKING
PATTERN WILL ERODE. THROUGH THE COURSE OF THE WEEK, SEVERAL
SHORTWAVES WILL RIPPLE OFF THE BASE OF THE TROUGH THROUGH THE CENTRAL
CONUS, YET THE STRONG HIGH PRESSURE WILL DIMINISH THESE SYSTEMS
BEFORE THEY CAN REACH US. LONG RANGE MODELS CONTINUE TO HINT AT A
FRONTAL SYSTEM NEARING THE TN VALLEY DURING THE SECOND HALF OF THE
WEEK, YET DIVERGE IN SOLUTIONS REGARDING THE PROGRESSION OF THE
FRONT. THIS CREATES SIGNIFICANT UNCERTAINTY REGARDING WHEN OUR NEXT
CHANCES OF RAIN WILL BE AND HOW MUCH RAIN WE WILL RECEIVE. IF THE
FRONT DOES MAKE IT THROUGH, MODELS REMAIN PESSIMISTIC WITH RAINFALL
AMOUNTS BELOW A TENTH OF AN INCH ON THURSDAY. UNFORTUNATELY, THIS FAR
OUT, IT IS STILL POSSIBLE THAT THE RIDGE AND HIGH PRESSURE WINS OUT
AND WE REMAIN DRY THROUGH THE END OF THE WORK WEEK. WE WILL KEEP AN
EYE ON THIS SYSTEM TO ASSESS IF IT WILL INDEED GRANT US ANY RAINFALL
OR IF OUR WARM AND DRY CONDITIONS WILL PERSIST.
