West Coast this week, while a cold front bring Arctic air to the
South and East Coast by Thursday and Friday ...

Wednesday and Thursday along and behind the Arctic front, as well
as mountain snow across the Southern Appalachians ...

...Showers and thunderstorms chances will prevail across central
and southern Florida Wednesday and Thursday along a couple of

The main synoptic weather pattern will be troughing and cold
weather along the east coast, while ridging and above average
temperatures dominates the West. For tomorrow, the Plains can
expect high temperatures in the low 70s across Texas to the middle
40s as far north as South Dakota. A dry cold front does look to
pass through the southern Plains tomorrow afternoon and will help
lower dew points and bring cooler morning lows in the 30s for
Thursday morning across Texas. However, temperatures in the
afternoon will quickly moderate on Thursday across the central
tier as highs reach the 50s and 60s for the heartland, around
10-15 degrees warmer than average for Mid-January. The West Coast
will remain 5-10 degrees above average as a persistent area of
high pressure remains over the area. In general, high temperatures
are expected to average in the lower 50s across the Inter-Mountain
West for the next few days. Southern California and Arizona will
be warmer in the 70s.

An Arctic cold front will move southward through the northern
Great Lakes tomorrow and drop temperatures into the teens and 20s.
The front will then progress south and east through the day
tomorrow and into Thursday morning. Temperatures are expected to
plummet behind the front as high temperatures on Thursday will
struggle to get out of the 20s for most of the east coast and Ohio
Valley. Thursday morning temperatures as low the middle 20s are
likely across the Deep South, and then even colder morning low
temperatures on Friday as the mercury may drop into the teens
across the Carolinas and into the middle 30s across central
Florida. Florida residents will need to be on the lookout for
falling Iguanas by the end of the week.

The strong cold front will bring favorable conditions for lake
effect snow downwind of the Great Lakes. Winter Weather Advisories
are active downwind of Lake Superior, Lake Michigan, Lake Ontario,
and Lake Eerie for Wednesday-Thursday morning. There is also a
Winter Storm Warning on the downwind side of Michigan for portions
of far northwest Indiana and southwest Michigan as travel
conditions will be hazardous due to a forecast 6-8 inches of snow
with wind gusts to 40 mph. Allow for extra travel time in
favorable lake effect zones. Additionally, there is a Winter
Weather Advisory for the southern Appalachians and the Blue Ridge
as 2-4 inches, max 6", of snow is forecast for the area. Winds
could be gusty as well along the ridges.

For those storm lovers, South Florida can expect scattered
thunderstorms tomorrow due to lingering moisture and daytime
heating. On Thursday, coverage is likely to be higher as a line of
showers and storms will accompany a cold front moving through the
area.
