May 13: Stormy Conditions Tomorrow, Next Week

Today was already much warmer than yesterday, and even ended up warmer than expected, with parts of the immediate NYC area reaching 70 degrees. This warm up should continue, and for the short term, we should not have temperatures as chilly as the last 4 days.

Tomorrow's Outlook:

Temperatures tomorrow should continue to warm up, with 80 degrees possible once again. The interior areas should have high temperatures in the mid to upper 70s, the immediate NYC area in the upper 70s to lower 80s, and the lower to mid 70s for the immediate coast.

Instead of the mainly sunny skies we saw today, however, tomorrow should bring thunderstorms. In the morning hours, light rain is expected, though the afternoon should be drier, with mostly cloudy skies. Meanwhile, as the cold front approaches from our west, thunderstorms are expected to affect the area during the late afternoon and evening hours. Some of these storms may be severe, potentially producing small hail and strong wind gusts. These storms should end by the overnight hours.

Weekend And Early Week Forecast:

This weekend should be mild and dry. The models have trended slightly warmer, with my latest forecast expecting high temperatures in the lower to mid 70s across the area, peaking on Saturday and Monday.

By Tuesday, however, stormy conditions return once again to the area. A storm to our southwest is going to approach, bringing along with it the potential for heavy rain and thunderstorms. The latest models have been consistent with the wet solution, showing 1 to 2 inches of rain, leading me to issue a Blue Alert for this storm, indicating a less than 30% chance of significant rainfall, which may be changed to an Orange Alert if the wet solution remains consistent. There is still some uncertainty with the timing, though it appears that the best time frame for the heaviest rain could be on Tuesday and Tuesday night, with additional showers and thunderstorms on Wednesday.

High temperatures on Tuesday will cool down once again into the 60s, due to the cloud cover and rain, though Wednesday should be slightly warmer, possibly returning into the 70s.
