August 30 Weather Hot Today Then Storms And Ida Flooding

Monday August 30 2021

Ida has been downgraded to a Tropical Storm this morning. This remains on a path to weaken and curve our way Wednesday. This will bring the risk of heavy rain and severe storms.

But first, we have one last HOT day with temps in the 90s and a Heat Index close to 100ºF, followed by late day pop up thunderstorms. After Ida, we will get a stretch of cooler and dry weather into the holiday weekend.

Note: More school busses are on the roads. Please be mindful of the Stop Sign Arm and kids crossing.

Morning Surface Weather

Tropical Storm Ida has winds down to 60 mph. This is moving to the North at 8 mph, and still expected to curve our way. Before that arrives, we have heat, humidity, and a separate round of storms to deal with.

This NAM 3 Km model shows the potential of thunderstorms after 4 PM. This is not precise, but helps with the idea of timing and movement. We can expect a little more activity than shown here.

Tropical Storm Ida

Forecast Track/Cone

Ida will weaken to a Tropical Depression, but remain a potent force for heavy rain and severe storms.

ECMWF Storm Animation:

Here we see the rain from Ida arriving on Wednesday, well ahead of the center passing through Maryland Thursday morning.

The heaviest rain is forecast to reach into central PA, but I have verification of recent storms to the south. I think we still need to watch that core rain field.
