April 18 Red Flag Warning For Fire Danger Today

April 18, 2023

Tuesday Morning Update

A strong storm located in southern Canada is responsible for the snow showers around the Great Lakes AND our developing wind. Since we are on the southern edge of its influence, the winds blowing down from the mountains will be dry.

Given our drought conditions and the downslope air flow, the net result will be warming with gusty winds that can exasperate any small flame.

The National Weather Service has issued a Red Flag Warning from Noon to 8 PM.

Morning Temperatures

Morning Surface Weather

Strong winds will build again between Low Pressure in Canada and High Pressure to our south. The snow showers will remain to our north in central PA and the Great Lakes.

RED FLAG WARNING

Enhanced Danger for brush fires to spread. This will be due to:

• Winds: 15 to 25 mph, GUSTING to 45 mph.
• Dry: Relative Humidity dropping to 8%.

Wind Forecast Animation

Push from the West will increase during the morning and peak in the afternoon! This will enhance the dry conditions.

Wind Forecast at 2 PM

Average wind will be 15 to 25 mph, gusts may reach 35 to 45 mph at times.

Afternoon Temperatures

A very wide spread of temperatures will be enhanced by more clouds near and north of the PA line, and more sun with the warm and dry winds from Baltimore and southward.

Wednesday Weather

With calmer winds, the morning may bring frost inland. Then a sunny day will allow temps to warm back up again.

Look Ahead:

Saturday Morning to Monday Morning

The next storm will follow the path of the last one through the Great Lakes. This will surge in warm winds that will build ahead of the storm Friday and Saturday, followed by a period of rain and thunderstorms, then a return of colder air to end the weekend.

7 Day Forecast

It looks like a repeating pattern: After the winds settle down, there may be inland frost tomorrow morning.

Then, warming up back to summer heat later this week.

RESTATING MY MESSAGE ABOUT DYSLEXIA

I am aware there are some spelling and grammar typos, and occasional other glitches. I take responsibility for my mistakes, and even the computer glitches I may miss. 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 during my second year at Cornell University. It didn’t stop me from getting my meteorology degree, and being first to get the AMS CBM in the Baltimore/Washington region. One of my professors told me that I had made it that far without knowing, and to not let it be a crutch going forward. That was Mark Wysocki and he was absolutely correct! I do miss my mistakes in my own proofreading. The autocorrect spell check on my computer sometimes does an injustice to make it worse. I also can make mistakes in forecasting. No one is perfect predicting the future. All of the maps and information are accurate. The ‘wordy’ stuff can get sticky.  There has been no editor that can check my work when I needed it and have it ready to send out in a newsworthy timeline. Barbara Werner is a member of the web team that helps me maintain this site. She has taken it upon herself to edit typos, when she is able. That could be AFTER you read this. I accept this and perhaps proves what you read is really from me… It’s part of my charm. #FITF
