.DISCUSSION...
Bitter cold continues with a Wind Chill Warning remaining in
effect till 11 am tomorrow (Monday). Will then transition to
advisory conditions, but did not do that with this package. Night
shift will have a better handle on that.

Next thing of concern will be the snow that moves into the SW
zones late Tuesday into Thursday. Amounts will be nearing 6 inches
but the time line will be too long for Watch/Warning concerns.
Advisory looks to be more likely.

Models have not handled temperatures 100 percent the past couple
days. But clouds do move in tonight that should keep too places
from reaching -40. Have been leaning more with NBM10 for temps
through at least Tuesday. Warmest area has been in the SE zones
where snowcover is thinest or non-existent.

Later in the week, upper ridge moves in and and an increased
surface pressure gradient may push some of this arctic out.
Current NBM likely too optimistic. NBM10 takes most places to 20
not till Sunday. TFJ
