Warm First Half

Unlike the last two weeks, where each day’s weather was similar to the surrounding days, the weather this week will be full of change and activity.

Today will start off the week with quiet conditions and comfortably mild temperatures.

High pressure building in behind yesterday’s cold front will keep the area dry today. Morning clouds will gradually dissipate, leaving more sunshine for the afternoon.

Winds will be light and variable during the daytime hours, but will eventually turn to the south and increase to 5-10 mph by this evening.

Afternoon highs will be in the mid 70s, though a few areas will probably end up in the upper 70s as well. Temperatures this evening will stick close to 60 with most areas slipping into the upper 50s by dawn Tuesday.

Tomorrow will be warmer as the south winds continue to bring warm air, and humidity, into the region. Highs will reach the low 80s and dewpoints will rise into the low and mid 60s during the afternoon.

A couple isolated showers and thunderstorms will pop up late in the day, especially across the western half of the region. Most areas will probably not see rain.

Wednesday may be the highest impact day of the week as a strong cold front moves in and interacts with the heat and humidity. Throughout the northeastern US, scattered showers and thunderstorms are likely, and with ample winds in the atmosphere, a couple could be strong.

Now, so far, the greatest chance for severe weather appears to be well southeast of the region, from eastern Pennsylvania into western New England. However, at least a few thunderstorms are expected in our immediate area as well.

The details of Wednesday will need to be resolved further over the next 48 hours, so continue to monitor the forecast.

Chilly Shot

Behind this front, a much cooler air mass will settle into place.

Thursday will have a mix of sun and clouds. Highs should still reach into the upper 60s for a second pleasant day this week. North and northwest winds will be a bit blustery, with a few gusts over 25 mph.

Low pressure will track to our south on Friday, bringing rain and cool air to the region. There are still questions on how far north the rain tracks, but at this point, it seems like most of the Finger Lakes should see some rain.

Temperatures Friday are likely to be chilly with the steadier rain. Highs may manage to get into the 50s, but there is a chance it may actually be in the 40s much of the day.

Next weekend looks dry, but temperatures will remain suppressed. Highs on Saturday will only be around 60 degrees, while Sunday reaches into the mid 60s. Morning lows both days should generally be in the 40s and frost is not expected to be an issue.

Most of the following week looks like a slow but steady climb in temperatures, getting us back into the 70s.
