…More winter weather for the Great Lakes Region…
…Arctic air currently engulfing much of the eastern U.S. will gradually
moderate over the next couple of days…
…The next storm system enters the West this weekend …
Conditions remain favorable for lake effect snow downwind of the Great
Lakes. Cold air, relatively warmer lake water temperatures, and persistent
northwesterly flow will be ingredients for some regions to see feet of
snow accumulations. Western New York and northwestern Pennsylvania are
under a Lake Effect Storm Warning into Saturday, with travel conditions
hazardous as high winds will help lower visibility due to blowing snow.
Further north into the shores of western New York along Lake Ontario, 1-2
feet of snow accumulations are possible through Sunday as lake effect snow
bands continue. Additionally, a series of fronts will be moving northwest
to southeast through the Great Lakes from Wisconsin/Michigan to the New
England region this weekend. This will add chances for snow on top of the
lake effect snow and will help reinforce the cold air over the region.
The cold air is entrenched over the eastern U.S. today; high temperatures
in the Deep South will be in the 30s and 40s this afternoon. Low
temperatures in the 20s will be possible across much of the southeastern
U.S. Saturday morning and generally lower 30s Sunday morning. Areas in
northern Florida are under a Freeze Warning and people should take cold
weather precautions and protect sensitive vegetation. High temperatures
should start to moderate across the east by Sunday as anomalously warm
temperatures across the central U.S. shift into the region. Highs should
be in the 60s and 70s Sunday across the Southeast and 50s and 40s across
the Mid-Atlantic and Northeast.
After a tranquil Friday, increasingly unsettled weather is expected for
the Pacific Northwest by the weekend. Rain showers and some high elevation
snow will return to Washington State and Oregon by Saturaday as the next
front moves through. The mountain snow and low-elevation rain will
progress farther inland, reaching into the northern Rockies by early
Sunday as a low pressure system begins to develop across the northern High
Plains into Alberta Province of Canada. Winter Storm Warnings and
Advisories are active across the northern Rockies through Saturday where
several inches of snowfall and some icing potential will create hazardous
travel conditions.Much of the remainder of the western U.S. will remain
dry and milder than normal as high pressure dominates.
Lastly, Texas and the eastern Gulf Coast will have a rather cool and wet
weekend as moisture streams in along a warm front and surface low in the
Gulf of Mexico. An upper level trough moving into the region may also help
support lift and help raise rain chances. A heavier rain threat may emerge
from the central Gulf Coast into the Mississippi Valley by Sunday. A
couple of inches of rain are possible and some isolated instances of
flooding may occur Sunday and heading into next week.
