DISCUSSION
OVERALL DRY CONDITIONS EXPECTED THROUGH THE END OF THE WEEK, WITH
TEMPERATURES REACHING UP THE 70S ON THURSDAY, LOWER 80S ON FRIDAY,
AND RH VALUES DROPPING DOWN TO 10% EACH DAY. ON SATURDAY,
ISOLATED-SCATTERED VIRGA SHOWERS ARE POSSIBLE (20-30% CHANCE) IN
THE AFTERNOON/EVENING. HOWEVER, WETTING RAIN IS UNLIKELY GIVEN THE
DRY AIR MASS AT THE SURFACE. IF A STRONGER STORM WERE TO OCCUR
OVER THE BURN SITE, EXPECT <0.10" OF RAIN ACCUMULATION. LIGHTNING
AND GUSTY ERRATIC OUTFLOW WINDS WILL BE THE BIGGEST THREATS.
THE BEST CHANCE FOR WETTING RAIN WILL BE SUNDAY, WHERE WIDESPREAD
SHOWERS/THUNDERSTORMS ARE POSSIBLE ACROSS THE AREA. AS
OF RIGHT NOW, THERE IS A 30% CHANCE OF 24-HR RAINFALL ACCUMULATION
>0.25" BY SUNDAY NIGHT (50-60% CHANCE OF ACCUMULATION >0.10").
MOISTURE WILL LIKELY LINGER AROUND ON MONDAY, WITH MINIMUM RH
VALUES HOVERING AROUND 40-50%. AFTERNOON SHOWERS ARE POSSIBLE, BUT
WETTING RAIN IS UNLIKELY GIVEN WEAK INSTABILITY.
VERY LOW CHANCE (<20%) OF AFTERNOON SHOWERS/THUNDERSTORMS BY
TUESDAY AND WEDNESDAY, WITH TEMPERATURES CLIMBING INTO THE 70S
AND 80S. A DRY AIR MASS IS EXPECTED TO MOVE INTO THE REGION, WITH
MINIMUM RH DOWN TO AROUND 20% ON TUESDAY, AND 10-15% ON WEDNESDAY.
