WINTRY MESS HEADS TO BEGIN THE WEEKEND

snowfall-potential-mapClouds return late towards evening ahead of our next system. Temperatures hold steady in the 20s this evening and overnight.  With the frigid air in place, the atmosphere is conducive to snow initially.  Snow will be light and fluffy which accumulates quickly.  But it’s through the area rather quickly which limits snow amounts.  Warm air quickly warms the upper levels of the atmosphere while the surface temperatures remain at or below freezing.  Snow ice-totals-mapmixes and changes to period of  sleet and freezing rain, bringing an accumulation of ice.  A coating to 2’ of snow in our southern counties is possible with maybe an additional 1 or 2 farther to the north and northwest but it depends on how when sleet and freezing rain mixes in.  That keeps amounts on the lower side.  Ice is more likely and may accumulate anywhere from a glaze to a

.10” of an inch in southern areas and more north with .25” of an inch possible. Spotty areas north and west may see even higher amounts.  This would cause significant traveling challenges. Not to mention the sidewalks, driveways and parking lots could become very slick for awhile before surface temperatures warm up.   The question is how long it takes for surface temperatures to warm.  Timing for precipitation to begin is around midnight in the west then it spreads east.  By 4am, a transition to sleet and freezing rain takes places and continues for a few hours. Around 11am we could see the wintry mix change to a few rain showers but much of the moistures is falling apart by then leaving cloudy skies.  The best time to venture out would be after the noon hour. This allows surface temperatures to warm above freezing and melt any ice which accumulated. Temperatures warm slowly through the day to the upper 30s, holding steady overnight.

As a cold front approaches, temperatures jump into the 40s early with a chance for rain showers.  The front is through early Sunday but the showers may linger into the afternoon hours and even mix with sleet and snow on the tail end as the cold air catches up to the precipitation.

High pressure brings dry weather for the beginning of the week. Plenty of sunshine but chilly for Monday and Tuesday.  We jump back to the 40s for the official start of the winter season on Wednesday.  We are still in the 40s for Thursday but our next system brings a chance for rain and or snow in the evening and overnight.
