...Lingering fire weather concerns for Southern California...
...Cold to linger across the Northeast through the rest of the week...
High pressure over portions of the West will help maintain warm and dry
conditions; which will prolong critical wildfire conditions for portions
of southern California. Poor air quality will persist across much of the
Pacific Northwest in this pattern as well. Rain, an mountain snow, will
begin to move inland Thursday afternoon as an upper-level trough and
associated surface front approaches the coast... spreading to the Northern
Rockies by Friday.
Cold, breezy conditions were observed for most of the Northeast and
Mid-Atlantic region today in the wake of the system moving out into the
Atlantic Ocean. A clipper system passing through the Great Lakes region
today will bring areal averages of 3 to 6 inches of snow from lower
Michigan to Pennsylvania. A vast major of this region has Winter Storm
Warnings and Winter Weather Advisories in effect. Lake effect snow showers
will continue downwind of the Great Lake through Friday but there will be
enough shifting of the wind direction to prevent much in the way of heavy
A weak system will push south through the Plains bringing light snow
showers(or a mix of rain and snow)... while another cold front sags
southward into the Southern Plains, Mexico and the Gulf of Mexico over the
next few days. South Texas could see a decent rainfall Friday into
Saturday as the cold front slows its pace.
