middle-level clouds across North Texas should spread
northward overnight early Wednesday. Otherwise breezy
south winds will prevail with VFR conditions.

we reduced rain chances earlier this evening as it became more
apparent that ingredients needed for storms would not be able to
overcome the negative factors over the great majority of our
forecast area. We have further reduced those chances with this
latest update...low enough that there should be no mention of rain
in text forecasts for tonight. The rest of the forecast still

VFR conditions will prevail. Southerly winds will diminish some
this evening but will increase overnight into Wednesday as the

a weak upper low will drift northward late this afternoon into
tonight...generating widely scattered showers and storms across
mainly southern Oklahoma and North Texas. A stray storm or two may
occur almost anywhere along and south of Interstate 40...but
confidence is rather low. Given last nights somewhat unexpected
convective complex...will maintain at least a mention of
showers/storms over much of the area through the evening hours.
Conditions do not appear as favorable for severe winds and hail
today as yesterday...but heavy rainfall...small hail...and gusty
winds may occur with stronger storms.
For the remainder of the week into the weekend...strengthening
middle level ridging should keep most areas dry. Again...a stray
storm or two is not totally out of the question...but coverage
will be too slim to include any mentionable probability of precipitation through at least
Saturday. Temperatures will also be on the rise...as 850mb temperatures
creep up...and southwesterly surface winds develop each day. This
should keep US rather hot and muggy into the weekend. Heat indices
of 98 to 104 degrees will be common most days.
Long range guidance continues to suggest a weak front may move
into the Southern Plains during the middle to latter part of next
week. However...the trend has been to slow this frontal
passage...and maintain Summer ridging for a longer period over the
southeast U.S. For now...will maintain seasonably hot and muggy
weather pattern through the extended period.
