Active storm track through early next week

7:24 AM
The strong low pressure system that developed over eastern Oklahoma late on Monday is now in the Ohio Valley and will continue to press north and east this morning towards western New York.  Heavy rainfall, which started last night, has continued through early this morning.  As expected, the heaviest rainfall was focused over southern [...]

Observed Rainfall Amounts Through Sunday

8:11 AM
The models over the past several days had been advertising a rather significant rainfall event for the forecast area.  The observations from the past two storms are in and here is the combined precipitation amounts from these storms.
I made a map based on the official National Weather Service Observations.  The heaviest rainfall occurred along [...]

Wet end of the week begins

7:16 AM
This morning, an impressive disturbance is diving south towards the Tennessee Valley and has begun to enhance rainfall over the East coast.  An area of low pressure off the South Carolina coast this morning, which developed last night during the live chat, is starting to intensify with a 2 MB drop in the past [...]

Update for the rest of today

9:15 AM
Through the early morning, heavy rain fell over much of the forecast area.  However, as the morning progresses the heaviest rainfall is coming to an end as the remnants of Danny, barely a tropical depression, will be focused over Connecticut and central/eastern Long Island.  For the rest of the forecast area, scattered showers will [...]

Another coastal storm threatens the region

9:15 PM
Once again, the weather pattern is acting more like mid October rather than mid July as a coastal storm begins to organize off the Southeast coast.
I studied all the model guidance from 12Z and 18Z this evening and found a basic overlying theme for the next 60 hours.  The brunt of the heavy rain [...]

Very Warm Today, Cold Air Is On The Way

6:06 AM
When you walk out this morning, you are going to be pleasantly surprised with how warm it is as temperatures are already rising through the 40’s this morning.  A strong cold front over the Ohio Valley will continue to slowly move towards the forecast area with rain entering the region by around 6 PM [...]

Progressive Pattern Winning Over Model Guidance

7:37 PM
Eventually the model guidance was going to have to come to grips with the fact that the overall pattern is a fast, progressive pattern.  As a result, the idea of a storm sitting just off the coast for several days as seen by some guidance yesterday is quickly losing favor.  
I don’t have too [...]

High Pressure To Give Way To Significant Storm On Wednesday Night

5:48 AM
High pressure is currently over central Pennsylvania and will slide east through the forecast area today.  Clear skies can be expected with winds slowly veering to the south and southwest over the next 24 hours.
A strong area of low pressure will develop over Kansas today and will move towards the eastern Great Lakes by [...]

Heavy Ice And Rain To Continue Through This Afternoon

7:27 AM
The forecast for the next three days is obviously going to be the most active in the next 24 hours.
Currently, a coastal low pressure system is developing off the New Jersey coast.  Winds along the coast are beginning to turn to the northwest over southern New Jersey and northeast along Long Island, clearly indicating [...]
