Short Range Forecast Discussion

Valid 12Z Mon May 10 2021 - 12Z Wed May 12 2021
...Widespread rain and thunderstorms are expected across the south-central
to southeastern U.S., with some severe weather and flash flooding
possible...
...Late-season snowfall is likely across the Northern/Central Rockies and
High Plains with much colder than average temperatures...
...Warm and dry conditions will cause fire danger in the southwestern U.S.
and California...
A slow-moving front is forecast to meander over the south-central and
southeastern U.S. over the next few days, and the front will help to focus
abundant moisture to cause widespread showers and thunderstorms across the
region. Today into tonight, severe thunderstorms is most likely for
portions of southern Texas as well as eastern North Carolina, where Slight
Risks of severe weather are in place from the Storm Prediction Center for
tornado, wind, and hail threats (southern Texas could see very large
hail). Some strong to severe thunderstorms cannot be ruled out along all
the Gulf Coast states as well. Additionally, heavy rain is possible and is
currently forecast to focus near the central Gulf Coast, and isolated to
scattered flash floods are possible there with a Slight Risk of excessive
rainfall and a Flash Flood Watch. Then on Tuesday, moderate to locally
heavy rainfall with thunderstorms can be expected for parts of Texas into
the Lower Mississippi Valley, and another Slight Risk of excessive
rainfall is in place for those areas. Meanwhile, farther north, surface
lows in the vicinity of the Northeast will help cause persistent showers
there, with light to moderate rainfall expected.
Upper-level energy and cold temperatures will lead to snow across the
Northern and Central Rockies. The highest elevations of Colorado and
Wyoming can expect well over a foot of snow. Even in lower elevations of
the Central High Plains, precipitation type could fluctuate and some may
fall in the form of snow. Cities like Cheyenne, Wyoming could see around 6
inches of snow, and Colorado Springs could see some accumulating
late-season snow too.
Temperatures are expected to be below average for much of the country
behind the potent cold front, especially by Tuesday. High temperatures in
central parts of the High Plains are forecast to be the most anomalous,
with temperatures around 30 degrees below average for this time of year.
In terms of cold low temperatures, Freeze Warnings and Frost Advisories
are once again in effect for portions of the Great Lakes region and Ohio
Valley this morning. Exceptions that will be warmer than normal are the
West Coast, especially California, as well as southern Texas and Florida,
with temperatures right around normal in the Southwest. Warm temperatures
and as dry and windy conditions should unfortunately once again cause
Elevated to Critical Risks of fire weather and Red Flag Warnings in
interior northern California and the Southwest/Southern Rockies/Southern
High Plains today. Conditions should improve somewhat by Tuesday.
