...Major early Spring storm to bring numerous weather hazards from

the Great Lakes, across the Ohio and Tennessee Valleys, the South,

Southeast and the Northeast...



...Heavy snows likely across much of Wisconsin, the U.P. of

Michigan, Northern New York State into central to northern New

England...



...Strong cold front to bring much cooler weather Wednesday from

the Ohio Valley into the Lower Mississippi Valley and South...



...A strong front to move off the Pacific, bringing much cooler

temps to the Pacific Northwest Wednesday, southward into all of

California by Thursday...



An active early Spring weather pattern on both coasts over the

next few days resulting in numerous weather hazards and dropping

temperatures.  An area of low pressure across the Mid-West Tuesday

afternoon is expected to strengthen rapidly today into Tuesday

evening as it pushes north into the Great Lakes.  This will be

followed by another area of low pressure developing across the

Mid-Atlantic Wednesday and pushing northeast into eastern New

England on Thursday.  The combination of these two areas of low

pressure will produce numerous weather hazards over the next 2

days.  Heavy snows are forecast to develop to the north of the

Mid-West low this afternoon and continue into Tuesday night and

Wednesday across portions of the Upper Mississippi Valley and

Upper Great Lakes.  Snowfall accumulation of 6-12"+ expected

across central to eastern Wisconsin into the central to eastern

portions of the U.P. of Michigan.  Winter Storm warnings are in

effect across these areas, along with Blizzard warnings across the

central U.P. of Michigan. 



Heavy Spring snows also likely to develop Wednesday afternoon

across northern New York State and spread into central to northern

New England as the second area of low pressure deepens along the

Mid-Atlantic and New England coasts.  Snowfall totals of 6-18"

expected across northern New York state, much of Vermont, New

Hampshire, much of Maine and portions of northern Massachusetts. 



To the south of the areas of heavy snows, heavy rains are expected

along and ahead of the strong cold front forecast to sweep

eastward tonight through the Ohio and Tennessee Valleys and across

much of the Eastern Seaboard from the Mid-Atlantic to Florida

during Wednesday.  The heaviest rain totals are expected from the

Upper Ohio Valley into the Central Appalachians and into the

Mid-Atlantic.  Widespread Flood watches are currently in effect

across these areas.  In addition to the heavy rain and flooding

threat, severe weather is also possible across portions of the

Ohio and Tennessee Valleys and much of the South Tuesday afternoon

and Tuesday night, and into the Southeastern U.S. on Wednesday. 



Much cooler temperatures are expected in the wake of this strong

front as it pushes eastward.  Much above average temperatures are

expected to stretch from the Lower Mississippi Valley, eastward

into the Ohio/Tennessee Valleys, South and Southeast on Tuesday,

being replaced by below average temperatures Wednesday and

Thursday behind the strong cold front.



A strong cold front also expected to push inland along the West

coast.  This will begin across the Pacific Northwest Tuesday

evening/night and then spread southward through all of California

and the western Great Basin on Wednesday.  Much above average

temperatures along all of the West coast Tuesday will be replaced

by below average temperatures spreading southward Wednesday and

Thursday behind the strong cold front.  In addition, precipitation

will be developing across large portions of the West coast, inland

into the Northern Rockies and Great Basin over the next two days

associated with the above mentioned front.  Overall precip totals

are not expected to be as heavy as past events across portions of

the West, but additional heavy snow amounts are possible across

portions of the central Sierra.
