...Spring cold front set to bring multiple rounds of heavy rain and severe
thunderstorms today and Tuesday across a large area stretching from the
Southern Plains and Mid-South to the Southeast...
...Heavy snow in the Central Rockies to diminish by tonight...
Much of the attention to start the workweek will be associated with a cold
front marching across the central U.S. today and into the East by
Wednesday. As this frontal boundary swings east-southeast, ample moisture
ahead of the system will lead to developing showers and thunderstorms.
Starting with today, the best chances for severe thunderstorms exist
throughout the Mid-South from southern Indiana to southeast Oklahoma.
Showers and thunderstorms are expected to form this evening and could
producing damaging wind gusts, large hail, and isolated tornadoes. The
Storm Prediction Center has issued an Enhanced Risk of severe weather
(level 3 out of 5) across the region. Elsewhere, a warm and humid airmass
in place could pose a risk for a few isolated severe thunderstorms across
the Southeast. Damaging wind gusts and hail will be a concern from Alabama
northeastward into Georgia and parts of the Carolinas through early this
evening. Downpours associated with the widespread shower and thunderstorm
activity may cause isolated instances of flash flooding as well.
By Tuesday, the aforementioned cold front is forecast to enter the Ohio
and Middle/Lower Mississippi valleys. As it does so, another round of
thunderstorms should develop and impact areas from the Deep South to Ohio
Valley. Strong wind gusts will be the primary concern associated with the
thunderstorm activity, with large hail and isolated tornadoes also a
possibility. SPC has issued an Enhanced Risk of severe weather for Tuesday
that includes central/eastern Louisiana, Mississippi, northern/central
Alabama, south-central Tennessee, and far northwest Georgia. Along with
the severe thunderstorm threat, flash flooding will also be a concern for
the same region. The combination of heavy rain and previously saturated
soils could lead to rapid water rises in flood prone areas.
A tale of two seasons will be found across the western half of the
country. Heavy snow is ongoing across the Central Rockies today, while
above normal temperatures and fire weather a concern in California. Winter
Storm Warnings and Winter Weather Advisories are in effect across northern
and central Colorado as up to a foot of snow could accumulate by tonight,
with the heaviest amounts expected along and just east of the Continental
Divide. Meanwhile, high temperatures 10 to 15 degrees above average will
be found to start the first full week of May throughout the Golden State.
The combination of warm temperatures, low relative humidity, expanding
drought conditions, and gusty winds cold produce an elevated fire weather
threat. Red Flag Warnings have been issued across Northern California to
highlight the potential for wildfires to spread uncontrollably.
