Rain Timeline Friday And This Weekend Then The Very Brief Warm Up

Thursday Night Update

If you did not get much rain today it is likely that was part of the plan. This evolving pattern had the rain locked up mostly across the mountains and foothills… not spreading eastward tonight.

The large upper-level pattern is the main event, and that will take full form later on Friday.

Much of the region may still end up with over 1 fresh inch of rainfall.

The expectation is that steady rain will develop and the possibility that it will blossom into heavy rain and maybe even some thunder Friday night underneath a cold and unsettled pocket of air in the jet stream.

The higher mountains can still expect snow, and a few inches are possible in the Poconos of Northeast Pennsylvania.

If you are making plans for the weekend, the rain should taper to showers on Saturday, but the ground will be soggy. That may affect kids’ sports.

If you have a choice or days to be outside, Sunday will dry out and warm a little. Then we will get up around 70F on Monday before the next push of late winter chill arrives next week.

We do need this rain AND it will make a small dent in the overall drought if this fully verifies.

Surface Weather Thursday Night

As the rain expands to the East Coast, the main energy and cold air that will feed into this storm is still following behind. All will catch up and warp up over our region on Friday.

Storm Animation

Friday Morning to Sunday Morning

The development of this slow-moving storm will produce a large field of steady rain and even mountain snow.

The Surface Low will pass off the coast on Sunday afternoon, hopefully taking the rain and chill with it.

Jet Stream Forecast Friday Morning to Monday Afternoon

The core of the upper-level low will pass to the Southeast US, locking in a cool and damp weather pattern in the Eastern US.

It will relax and allow a brief ridge to push in warmer air on Monday.

FRIDAY WEATHER

Radar Simulation 8 AM to Midnight

Rain will expand and become steady, then heavy later in the afternoon and at night. There may be some rumbles of thunder mixed in.

Snapshots

These plots are suggestions and not perfect. The main idea is the expanding rain in the coverage area and intensity throughout the day.

I have highlighted the circulation of the rain bands with the upper-level winds… They will wrap overhead and nearly stall Friday night.

Friday Morning

Rain expands across Central Maryland and Bay areas.

Friday Afternoon

Rain will become more widespread during the day.

Friday Evening

Rain will become heavier through the evening and night.

Midnight

The heaviest rain across Central Maryland to Southern New Jersey may include some rumbles of thunder.

SATURDAY WEATHER

Saturday Morning

A chilly rain to start the day, while slushy snow may accumulate over the higher mountains… especially in the Poconos.

Saturday Afternoon

Rain showers may linger under the cold air. Not a washout, but the ground will be soggy from the day before.

Saturday Night

Rain showers may linger, but not a washout.

Sunday Morning

This storm should wind down and slip away as we end the weekend.

Rainfall Total

National Blend of Models

This brings most of our region over 1 inch in total.

Jet Stream Next Week

Monday Snapshot

This is the day that we can expect to reach 70F.

Monday to Wednesday

There will be one more push of cold air in the middle of the week. Perhaps this is the last one for a while and we can get back to spring locked in after this passes.

Wednesday Snapshot

This pocket of chilly air will be modified with more sunshine. Morning temps may drop to freezing inland, but it should not be as cold as this past 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 the 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 at predicting the future. All of the maps and information are accurate. The ‘wordy’ stuff can get sticky.  There has been no editor who can check my work while writing and to 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 available. 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
