July 28: Cooler Weather Starts Friday

Blog Updates: Both the 5-Day Forecast and the Severe Weather/Tropics pages have been updated today.

—————————————

Today was again a mainly sunny day, however temperatures were warmer across the area, returning into the 90s for the immediate NYC area. This isn’t likely to last for long, however, as a cold front moving through tomorrow will bring cooler temperatures to the area that will last for a few days.

Tomorrow’s Outlook And Storm Potential:

A cold front is expected to move through late tomorrow morning or the early afternoon hours. It appears that the cold front’s timing will not be supportive for severe weather, however with precipitable water values near 2 inches, locally heavy rainfall is a possibility with an area of storms likely to move through during the morning hours inland, late morning to early afternoon for NYC, and afternoon hours for Long Island/S CT.

High temperatures will be slightly cooler than today, with humid conditions likely early in the day. High temperatures will reach the mid 80s inland, upper 80s to lower 90s for the immediate NYC area, and mid to upper 80s for Long Island and S CT.

Friday And Weekend: Chilly, Then Rainy

Friday and Saturday will both be much cooler and less humid, with high temperatures dropping into the lower to mid 80s inland and for Long Island/S CT, with mid 80s likely for the immediate NYC area, with a few upper 80s possible. Dry conditions are expected for both days.

Rainy conditions return again by Sunday as a disturbance approaches the area. Scattered showers and thunderstorms are likely between Sunday and Monday, some of which could produce heavy rain. The GFS model, which has been updated with new features today, shows 1-2 inches of rain for the area, though this may be too much. High temperatures will be in the upper 70s to lower 80s across the area for both days.

After the rain moves out, a warmer air mass returns once again. High temperatures will reach the upper 80s to lower 90s again, with the next potential of rain for late next week.
