Pinpoint Weather: Mild conditions today yield to brisk and crisp pattern Wednesday as temps will be “upside-down”

Weather Blog

The quiet and calm weather scenario of today will be quickly replaced by a taste of winter Wednesday. There is a good deal of cold air poised and ready to arrive by the middle of the day Wednesday along with a few showers and even a wintry mix in the mountains.

A strong cold front is likely to cross the Commonwealth early in the day and provide a bit of rain, but more impactful will be the wind and a brief return to winter. The mercury in the thermometer will drop as the day moves along and should be in the upper 40s by the evening commute. This is referred to as an upside-down temperature day with the highs occurring well before the usual time in the afternoon.  Winds ahead of the front will be from the south and a bit from the southwest then sharply shift to the west and northwest by the middle of the day. The rain and wintry mix are not going to be all that robust, but that is not the main feature of the day.

Cold, brisk and crisp will be the best way to define the day Wednesday as the bitter air arrives in the middle of the day.  The normal high should be around 70 east of the foothills, but we will be in the 40s by sunset. The record books will show a high in the upper 50s to low 60s, but that will be achieved before noon, afternoon temps will generally be in the low 50s. 

Here are the estimated temps for the morning and then in the afternoon. You can see the temps are milder at 9am than at 2 pm. Upside Down with respect to the normal daytime heating.

Frost and freeze products have been issued by the NWS for overnight Wednesday into Thursday as tender vegetation may be in peril due to the cold. Please tend to your perishable plants today and tomorrow to keep them from burning in the cold.  Winds will be howling both Wednesday afternoon, overnight into Thursday and on Thursday making it feel a bit cooler than what is being recorded on the thermometer. 

Thursday should be dry and brisk as the front pulls away and the cooler air and wind remains.  There will be plenty of sunshine Thursday and Friday as the wind clears the air. Friday will be a bit more normal as far as temps go with highs in the upper 60s. Sunny and mild will be a good way to describe the last day of the work week.

Saturday will be the wet day of the period. An area of low pressure is slated to push through to the coast and generate a good deal of rain for the region.  The low will be producing rain most of the day and the rain may be heavy at times so expect to see a chance for some minor flooding.

Sunday will see the rain exit before mid-morning or maybe before sunrise. A cool and pleasant day will be left in the wake of Saturday’s low, but some winds may be present to drop a bit of a fly in the ointment. Overall, Sunday will be a day of drying and then a warmer pattern arrives next week.
