July 23, 2013 Storm Updates

1:25 AM: Strong Storms Approaching NJ, NYC

Throughout the afternoon and evening hours yesterday, widespread showers and thunderstorms developed across Pennsylvania and New Jersey, slowly expanding and spreading northward into New York along and north of a stalled frontal boundary over the area. These storms were generally non severe but produced heavy rainfall, with radar estimates showing 3/4 to 1.5 inches of rain in most of northern NJ, locally up to 2-3 inches especially in Morris county. Locations east of NYC, however, have yet to see more than a few isolated storms.

Most of the heavy rain and storm activity shifted north into NY state as expected, although a severe thunderstorm developed over southeastern PA and is slowly tracking northeast towards western-central New Jersey. The stalled frontal boundary is currently located near northern NJ into NYC on a west-east axis, and the storm is expected to weaken in severity once approaching NYC, although it will be capable of producing heavy rainfall over the next few hours especially west and southwest of NYC, with gusty winds also a risk.

The frontal boundary will gradually lift north as the wave of low pressure organizes over the region and tracks northeast, with occasional showers/storms continuing through the mid-late morning, mostly north/west of NYC, while the heaviest rain stays north of the area. Another 1/2 to 1 inch of rain is expected north and west of NYC, with less than 1/2 inch to the east. Most of the current heavy rain activity should clear the region in the morning, although additional scattered storms are expected to develop in the afternoon and evening, which also may be capable of locally heavy rain. The next update will be posted later this morning.

July 22, 2013: Occasional Storms Today, Tomorrow

Forecast Highlights:

A weak frontal boundary slowly shifted through the region yesterday, with temperatures falling back down to near average as the hot and humid air mass from last week was pushed offshore. This frontal boundary will remain near the region through the rest of the week and weekend, with occasional rounds of showers and storms, such as today and Tuesday and possibly next weekend, continuing into at least early August.

July 21, 2013: Rain Returns This Week

Forecast Highlights:

A cold front that slowly approached the region in the last few days is moving through today, bringing an end to the 7-day heat wave for most of the region, although some locations are still expected to reach the low 90s today. The frontal boundary will stall nearby most of the week with occasional rounds of scattered storms and thunderstorms, especially in the middle of this week and possibly next weekend, with high temperatures cooling back down into the 80s.

July 20, 2013 Noon Update

4:25 PM: Scattered Storms Developing

A weakening cold front is slowly approaching the region, producing scattered showers and thunderstorms. The latest radar, posted to the left, shows scattered strong storms in southern New England and the Mid Atlantic region; although there is plenty of instability, mid level lapse rates are marginal and bulk shear is lacking, which should prevent significant severe weather across the region today. Isolated to scattered storm coverage will continue through this afternoon and evening, with some storms becoming strong with locally heavy rain and gusty winds, before ending tonight as the cold front slowly moves through, bringing a less humid but not much cooler air mass as high temperatures remain stuck in the mid 80s to low 90s.

The next update will be posted on Sunday morning with more information on this coming week's outlook.

July 19, 2013: Cooler Weather Returns Sunday

Forecast Highlights:

The heat wave that affected the region since last Sunday reached its peak today for most, with widespread highs in the mid 90s to low 100s away from the coast, where a sea breeze and isolated storms kept temperatures cooler. Along with humidity, heat index values got up to the mid 100s to even low 110s. A weak cold front will produce some storms tomorrow as it comes through, ending the heat wave, with temperatures returning into the 80s with some rain chances next week.

July 18, 2013: 100 Degrees Today And Tomorrow

Forecast Highlights:

The peak of the heat wave takes place today and tomorrow, as more westerly winds and warmer temperatures aloft bring temperatures into the mid to upper 90s across the area, with low 100s possible in parts of NE NJ or NYC. Along with humid conditions, heat index values will reach the low-mid 100s, possibly even higher locally. A cold front will produce thunderstorms on Saturday evening, ending the heat wave, although the severity of the storms may not be as significant as originally forecast.
