Today and tonight...An upper short wave combined with some decent
moisture rapping around the surface high may kick off a few
showers and possible a thunderstorm, mainly along and south of
I-20 this afternoon. This activity will quickly diminish after
sunset this evening. High temperatures will be a few degrees
hotter today, mostly in the low 90s. Surface high pressure will
strengthen over the area tonight, with clear skies and lows mainly
in the mid 60s./15/
Thursday through Monday night: The omega block with ridging over the
central CONUS will last through Monday even as the ridge axis shift
to become centered nearly over the Mississippi river. The surface
ridging from the northeast will continue over our region as well.
This will allow for a warming trend through the period highs topping
out in the mid to upper 90s by Monday. The surface ridge will
continue to help limit moisture return and although it will be hot,
the lower relative humidity will mitigate and heat stress concerns
as peak heat index values look to remain below 105F. the latest
Drought Monitor is showing abnormally dry to moderate drought
conditions across our northern zones. Without any rainfall in the
forecast along with the hot temperatures, conditions are expected
to worsen. /22/
