Late thunderstorms for some break heat

Hot, Then Some Storms

Another hot and humid day is ahead for the Finger Lakes, but a cold front will trigger some thunderstorms.

Clear skies dominate the region this morning, but some clouds and a few showers left over from a major severe weather outbreak across the Midwest yesterday are tracking across southern Ontario.

Some of these may work across the region late this morning and into the midday hours. Trends will have to be watched in case any early thunderstorms develop. At this time, though, this is not expected on a large scale.

Instead, temperatures will continue to climb, breaking into the 90s for many areas. Dewpoints in the upper 60s will produce heat index values a couple degrees higher than the temperature. Heat advisories are in place for most of the same counties as yesterday as a result.

The best chance for some thunderstorms will come after 3 PM. A narrow line of thunderstorms may develop. These storms seem most likely along and southeast of a Syracuse-Corning line.

With little support from the upper atmosphere, severe weather is not expected for the most part, but I cannot rule out an isolated damaging wind gust or two. Even outside of any thunderstorms, southwest winds will gust 20-30 mph today.

A few scattered showers will be possible behind the line during the evening hours as the front makes its way through. Temperatures will fall back into the low 60s overnight with a few clouds lingering early Wednesday morning.

Still Warm, and Dry

The front will settle well to the south and will stall out across the Mid-Atlantic and Ohio Valley. The air behind the cold front will be cooler, but still plenty warm and above the seasonal averages.

Wednesday will have increasing amounts of sunshine and highs topping out in the low and mid 80s. Thursday will be similar, but with more mid 80s and fewer low 80s.

Sunny skies will continue into Friday with temperatures holding steady in the mid 80s for most areas.

The quiet weather should hold into the weekend as well. Neither Saturday nor Sunday are expected to have any rain in the area.

High temperatures on Saturday will be in the mid to perhaps upper 80s. Sunday may see some 90s return to the area.

A front should approach the region by next Monday with a chance for showers and thunderstorms. This front will be stronger than today’s and should have actual cooler weather behind it, at least for a couple days.
