April 27 Weather Chilly Winds And A Freeze Watch Tonight

April 27 2022

Wednesday Morning Report

Cold air is filling in now with a brand new air mass for us.  The Eastern US is in a late winter-like pattern. This will include a chilly wind with Lake-Effect showers developing.  The net result will keep temperatures well below average, including overnight temperatures down into the 30s or colder. That is what has prompted a Freeze Watch, while a wider net can be cast for like frost over the next two mornings.

A warm up will begin by Sunday and early next week, which will include the return of thunderstorms as well.

FREEZE WATCH

With a clearing sky and light winds, temps will TANK tonight. This is the first level of awareness. This region is likely to be upgraded to a Freeze Warning, with the addition of a Frost Advisory for a larger area… especially inland from the water.

Take the time during the afternoon to cover your sensitive plants and bring in potted plants.

Thursday Morning

This is the coldest potential outlook showing the freezing line very close to Baltimore.

The most important take away is that many inland areas may reach the 20s. That means freezing for many hours, increasing the threat to plants.

Also, mid 30s will reach deep into Southern Maryland and even the beaches.  So most of our region has the chance for Frost Thursday morning, which will be a threat to newly sprouting crops and potted plants.

Thursday Afternoon

7 Day Forecast

Widespread Frost or Freeze  Thursday and Friday mornings.  That’s a plant killer for sure.

This weekend we been a warm up, with top temps before thunderstorms on Monday afternoon.

*Disclaimer due to frequent questions:

I am aware there are some spelling and grammar typos. I have made a few public statements over the years, but if you are new here you may have missed it:

I have dyslexia, and found out at my second year at Cornell.  I didn’t stop me from getting my meteorology degree, and being first to get the AMS CBM in the Baltimore/Washington region. 

I do miss my mistakes in my own proofreading. The autocorrect spell check on my computer sometimes does an injustice to make it worse. 

All of the maps and information are accurate. The ‘wordy’ stuff can get sticky. 

There is no editor that can check my work when I need it and have it ready to send out in a newsworthy timeline. 

I accept this and perhaps proves what you read is really from me…

It’s part of my charm.
