Winter Weather Advisory Extended Sunday Morning Then More Ice After

Sunday February 14

Happy Valentine’s Day! The weather gives the excuse to stay inside longer. A Winter Weather Advisory has been extended for most of the region until 10 AM. The reason is the lingering ice, but we can forecast and track the thaw today.

There was some freezing drizzle overnight that did not show well on radar. There are also areas of fog this morning that can add just a glaze to surfaces. On top of that, the ice in place remains while temperatures continue below freezing.

Travel: Main roads have been treated and are OK. Side roads, sidewalks, some overpasses will be where you will find ice last longer. Will improve by mid day.

Below is a look at the temperature timeline.

Quick Cast:

Morning: Icy
Afternoon: A chance to ‘thaw’
Tonight: Band of freezing rain and rain.
Monday Night: More Freezing Rain and Rain
Tuesday: Warming/Thaw
Thursday: Another storm, but this looks stronger and colder: Snow and Freezing Rain

Winter Weather Advisory

This expires at 10 AM, but ice in place will take even longer to melt.

Southern PA has a ‘Special Weather Statement’ where ice is more isolated but present on bridges, overpasses, and some rural roads.

We will gradually thaw and get the assist from solar radiation today. However a little freezing rain may pass on the north side tonight, then we have a fee more winter events during the work week.

Note: Thick ice on top of snow extends into Virginia. This will chill the atmosphere a little more than modeling might showing. We need to consider that forecast maps might adjust a little as we get closer…

Overnight Ice?

There will be a quick disturbance that may drop a few hours of rain or freezing rain.

If you are above freezing at sunset, you may remain just warm enough with this round.

Next Event: Monday Night-Tuesday

There may not be a way to win this one. Look at this temperature spread. A slight shift in any direction of 50 to 100 miles (which is small with weather), can bust the ice forecast zone.

Tuesday Morning Temperatures

Look at this spread from 0s in Ohio to 60s on the Maryland Eastern Shore.

The arctic air is so close, but being battled by this storm pattern. Again: Any shift of 50 to 100 miles can make a huge difference in where the icy weather sets up.
