…Severe Weather potential over the Southern Plains and Lower Mississippi
Valley today…
…Storm system brings unsettled weather to the West…
…Critical Fire Weather Risk over parts of the Southern High Plains for
the rest of the week…
…Warm temperatures across the Central and Eastern U.S….
A vigorous shortwave and surface low pressure system is tracking across
the Southern Plains today which will lead to showers and thunderstorm
developing this evening across the ArkLaTex and Lower Mississippi Valley
region. The Storm Prediction Center issued a Slight Risk of Severe
Thunderstorms over parts of northeast Texas, southeast Oklahoma, western
Arkansas and northwestern Louisiana where large hail and localized wind
damage are possible beginning this afternoon and continuing into early
Thursday morning.
For the West, an amplified upper trough will move ashore today, spreading
Pacific moisture, cooler air and strong winds across the region. Powerful
wind gusts of 40 to 70 mph combined with heavy snow will create
treacherous to potentially impossible travel below many major passes
across the Sierra Nevada and northern California higher terrain into
Thursday. Snowfall accumulations of 1 to 3 feet, possibly higher, along
with the high winds could cause scattered power outages. Heavy snow above
5000 feet and high winds will cause widespread hazardous travel over much
of the southern Intermountain West and Rockies Thursday into Friday.
Periods of heavy rain with rates of 0.5″/hr are likely in parts of
southern California through Thursday morning will keep an elevated threat
for flash flooding, including shallow debris flows across sensitive burn
scars or isolated rock slides, as well as hazardous travel due to ponding
of water and slick roads.
Persistent dry, warm and windy conditions will promote Critical Fire
Weather conditions across the Southern High Plains through the rest of the
week. Upper-level ridging will support above average temperatures across
the Central and Eastern U.S. for the next few days. High temperatures in
the 50s, 60s and 70s over the Midwest and Northern Plains will represent
20 – 40 degree anomalies through the end of the work week.
