Wednesday Overview: Hermine still hanging around

/1 Comment/by

You may have noticed some periods of squally, windy showers last night. Yes, that was actually from Hermine (or the remnants of it, anyway) — the system that we all just want to go away keeps finding a way to hang around. A blocking pattern captured the storm and allowed it to come back towards the area, fortunately  in a much-weakened state. But the weakening and transition to extra tropical in nature allowed some rain bands to expand away from the center of the storm, and back in to our area from the east.

The same general theme will continue on Wednesday, though with the storm continuing to weaken, the rain bands will be lessening in coverage. Some day-time heating may still try to enhance a few rain bands, but they will continue to be isolated to scattered in coverage and there may not be much at all west of I-95. We may see breaks of sun again — particularly for inland areas — as a large ridge builds into the area. This large ridge would be giving our area a heatwave had it not been for Hermine.

Heat returns to East, but active pattern awaits

The remnants of Hermine are still hanging around, off the coast of New Jersey and south of Long Island this afternoon. The system, in fact, has drifted farther south today than it has been all week — much to the ire of meteorologists and forecasters up and down the East Coast. Nevertheless, the storm will begin to have a lessening impact on our areas weather as the days of this week go on. The system is vertically stacked, at all levels of the atmosphere, meaning it’s cut off from moisture and lift sources.

Accordingly, the storm will fade out slowly over the next 24 to 48 hours, with only momentum carrying its circulation. As it does so, a large mid level ridge will build across the East Coast and Western Atlantic, as we have seen several times already this summer. This pattern looks to remain in place through the weekend, when temperatures will again approach the 90’s in many areas.

TS Hermine expected to impact NJ, NY Shores

/by

Tropical Storm Hermine, is reemerging over the open waters off the Mid Atlantic coast today. The storm is expected to re-strengthen before turning more north and west, closer to the coasts of New Jersey and New York. A prolonged period of onshore winds and heavy rain is expected resulting in the potential for coastal flooding, beach erosion, and localized damage from wind.

Hermine strengthens, tropical storm watches for NJ Shore

Hurricane Hermine strengthened in the Gulf of Mexico this evening, and continues to strengthen as it approaches the Florida Panhandle. Impressive satellite and radar imagery showed bursts of convection around the developing eye-wall of the storm, moving northeastward. Hermine is expected to make landfall along the Florida Panhandle before moving northeastward into the Southeast US.

After a short period of time in the Southeast United States, Hermine is expected to move northeastward and eventually re-emerge off the Mid Atlantic coast this weekend. Forecast models are in good agreement that the storm will track off the Mid Atlantic coast while interacting with a disturbance dropping southward over the Ohio Valley, which will eventually phase with Hurricane Hermine and tug the storm back westward toward the East Coast late this weekend.
