...Wet snow and high winds across the northern High Plains today

are expected to gradually become less intense by tonight...



...Mixed rain and wet snow spread east across the northern Plains

into tonight as showers and thunderstorms move across the Midwest,

Mid-South, Great Lakes toward the central Appalachians Monday

morning...



...Threat of heavy rain quickly emerges across the western Gulf

states later on Monday and then expands further into the Mid-South

by Tuesday morning...



...Critical to Extreme Fire Weather Risk continues over portions

of the central/southern High Plains today with improvements on

Monday...



An intense low pressure system, likely reaching peak intensity

early this Sunday morning, has continued to impact much of the

High Plains and nearby Rockies with winds locally gusting over

hurricane force.  The cold air mass behind this intense storm is

supporting wet snow across the northern High Plains into the

northern Rockies.  The combination of wet snow in the midst of the

high winds has resulted in blizzard conditions locally over

western Nebraska.  Meanwhile, plenty of warm air is wrapping

around the eastern side of the storm with bands of showers and

thunderstorms sweeping through the northern and central Plains. 

The intense storm is expected to gradually weaken today as it

moves generally toward the upper Midwest.  Mixed rain and wet snow

are expected across the northern Plains by tonight as showers and

embedded thunderstorms move into the Great Lakes and down the

Mississippi Valley by early on Monday.  The rain/snow over the

northern Plains is expected to taper off by Monday night when the

low pressure system weakens further and heads toward southern

Canada by Tuesday morning.



Meanwhile, the huge circulation associated with the weakening

nor'easter has been slow to exit New England, with some wet snow

and rain still affecting Maine and the Cape Cod area early Sunday

morning.  The precipitation is expected to taper off this morning

as the huge storm begins to move out into the Atlantic.  Colder

air wrapping around the huge storm will lead to below freezing

temperatures as far south as the southern Appalachians early this

morning before the April sun and the arrival warm air from the

intense storm over the Plains send temperatures well up into the

60s to near 70 by this afternoon.



For the total solar eclipse that is scheduled to take place on

Monday, it appears that southern Texas will wake up to

considerable clouds Monday morning with a resurgence of warm and

moist air from the Gulf of Mexico.  In contrast, New England will

likely wake up to clearing skies with cold temperatures into the

20s Monday morning under a fresh snow cover from the recent

nor'easter.  There will probably be some breaks in the clouds from

northern Arkansas to central Ohio behind a front, and mostly

cloudy farther northeast from eastern Ohio to western portions of

New York.



Beginning late on Monday into Tuesday, a threat of heavy rain will

quickly emerge across the western Gulf states and then expands

further into the Mid-South in response to a return of Gulf

moisture which will then interact with an upper trough arriving

from the southern Rockies.  In contrast, very dry conditions

combined with strong downslope winds from the Rockies will keep

fire danger at critical to locally extreme levels across the

central to southern High Plains with some improvements on Monday. 

Meanwhile, moisture from the next Pacific system is forecast to

bring the next round of precipitation into the Pacific Northwest

by later on Monday into Tuesday.
