...Severe weather likely across portions of the central and eastern U.S....
...Record warmth expected from the Midwest to the East Coast...
...Enhanced wildfire danger across the southern Rockies to the southern
Plains today...
Unseasonably warm temperatures will be in place today from the southern
Plains into the Midwest ahead of a strong cold front. High temperatures
will range from the 60s and 70s from the Ohio Valley through the
mid-Mississippi Valley eventually reaching the 90s across south Texas.
These temperatures will be a good 10 to 25 degrees above late February
averages. Besides warm temperatures, other ingredients will be present
today to support a threat for severe weather of all types from the
ArkLaTex into the Ohio valley, including tornadoes, large hail, damaging
straight line winds and flash flooding. The Storm Prediction Center has
highlighted locations from central Arkansas to much of Indiana with an
enhanced risk of severe storms for today through tonight. Farther south
and west, high winds and low relative humidity across the southern to
central High Plains will support a wild fire threat today behind a dryline
which will extend north to south across central Oklahoma and Texas. Winds
could gust to 60 mph from eastern New Mexico into parts of west Texas.
As the strong cold front advances east for Wednesday, the anomalously warm
temperatures and severe weather threat will shift east, affecting
locations from the lower Mississippi Valley to the Southeast and
Mid-Atlantic states. Temperatures are forecast to break daily high
temperature records for today and Wednesday in advance of the cold front.
Temperatures will only fall to near average behind the cold front as the
very cold air is locked up in northern Canada for the time being.
Winter weather in the form of light to locally moderate snow will affect
portions of the upper Mississippi Valley into the northern Great Lakes
region late tonight. Rain is forecast to change to snow as colder air
filters in behind a strengthening surface low tracking from the Midwest
into southern Ontario. Accumulations should be focused from southern
Wisconsin into Michigan storm totals are expected to be largely below 6
inches through Thursday morning.
After light coastal rain and mountain snow for the Northwest today, the
remainder of the West Coast will see a break from precipitation through
the middle of the week. Temperatures will continue to be near or below
average with the next round of noteworthy precipitation expected to reach
the Pacific Northwest toward week's end.
