…Thunderstorms and heavy rain possible over parts of the Southeast then
into the Mid-Atlantic…
…Record heat continues for the Northern Plains…
…Toasty Tuesday in Texas…
A slow-moving storm system over the Southeast today will move slowly
eastward/northeastward over the next two days. With a moisture feed from
the south (Gulf into the Atlantic), locally heavy rain and thunderstorms
are possible this evening/overnight and again Monday from the Florida
Panhandle northward into Georgia and northeastward into the Carolinas.
There is a Slight Risk (level 2 out of 4) of excessive rainfall through
Tuesday for some areas — flash flooding is possible within and near the
risk area. Temperatures will be cool in the Southeast due to abundant
cloud cover but will modify as the system exits the region.
In the West, an incoming storm system will bring in some showers (snow for
the higher mountain regions) and cool temperatures first over
Washington/Oregon/Idaho/Northern California then into the Great Basin and
Interior West. Ahead of the front, it will be fairly windy over much of
the interior region into the deserts this evening and again on Monday.
Some areas could see stronger winds (gusts over 50mph) tomorrow which
could make for difficult driving for high profile vehicles. Rain and
mountain snow will progress to the southeast on Tuesday into Utah and
Wyoming. Warm/hot temperatures over the Southwest today will be replaced
by temperatures 10-30 degrees cooler by Tuesday.
Over the Northern Plains, hot/record high temperatures today will persist
through Tuesday, along with windy/dry conditions. Red flag warnings are in
effect for the rest of today (Sunday) as Elevated/Critical fire weather
conditions remain in place. Temperatures will soar into the 90s to around
100F from the Dakotas into Minnesota which will break daily record high
temperatures Monday and Tuesday. Moderate to Major HeatRisk levels are
forecast for this region — stay hydrated and out of the sun during the
hottest part of the day. Farther south over Texas, mild temperatures today
(70s/80s) and Monday (80s to low 90s) will rise further on Tuesday ahead
of the western system. Widespread 100F readings are likely over much of
the Lone Star state which may eclipse record values. HeatRisk values will
increase into the Moderate category as the heat looks to continue past
Tuesday.
