...Inland snows and heavy coastal rains expected with a surface low
tracking through the northern Gulf of Mexico and up the Eastern Seaboard...
A surface low just off the Texas coast is expected to steadily track
eastward across the northern Gulf of Mexico...before lifting towards the
Eastern Seaboard late this week. Strong southerly flow ahead of the low
will pull an abundance of Gulf moisture northward and fuel widespread
precipitation across the Deep South on Friday. Heavy rains and
thunderstorms will be possible for locations along the coast...while back
beneath the upper energy supporting the surface low...conditions will be
cold enough for snow across portions of New Mexico and west Texas.
Precipitation will spread northward into the Mid-Atlantic states and
southern New England as the low begins to lift up the Eastern Seaboard
Friday night into Saturday. Heavy rains are again expected for coastal
locations and a mix of snow and sleet will be possible farther inland
within the northwestern edge of the precipitation shield.
Elsewhere across the nation...a system dropping down from central Canada
could cause a wintry mix of precipitation while it sweeps through the
Upper Great Lakes late this week. A series of Pacific systems moving
inland will keep conditions wet in the the extreme northwestern corner of
the Nation; however the rest of the West will stay quiet beneath a
sprawling surface high.
