Temperatures will soar into the 70s today before showers, and a few rumbles of thunder, arrive for tonight and Friday.

Southerly winds between high pressure just off the coast of the Mid Atlantic and a storm system moving into the Great Lakes will transport warm air north into the Finger Lakes.

Combined with sunny skies during the first part of today, this will push temperatures well into the 70s by this afternoon.

Clouds will start to move in from west to east this afternoon. Along with the clouds, a few spotty showers may work in as well, with showers becoming more widespread this evening. Showers will continue overnight and into early Friday. A few rumbles of thunder cannot be ruled out, especially towards dawn Friday.

A lull in the precipitation is likely later Friday morning, allowing temperatures to climb back into the 60s, if not warmer. The atmosphere will be favorable for a couple more showers, and maybe a few thunderstorms, to develop during the afternoon. Any sun that breaks out will increase the temperature and chances for thunder.

The cold front will finally slide through Friday night. With cloudy skies, temperatures will fall back to near or slightly above normal values in the low 40s for Saturday morning. Skies will clear early in the day Saturday, leaving the area with a deceptively sunny day.

The sunshine will be deceptive thanks to a breezy northwest wind. As this wind crosses Lake Ontario, the already chilly air will be modified by the cool lake waters, resulting in temperatures struggling to reach 50 degrees Saturday. The winds will die down for Sunday and temperatures will rebound back towards 60 degrees.

Monday and Tuesday remain very uncertain thanks to a front that will develop. This strong front will separate temperatures in the 40s from 60s and 70s by a mere 30 miles. Where exactly that front sets up will determine the temperatures early next week, as well as the rain chances.

There has also been some buzz about the chances for snow early next week. While there is an outside chance for some snow to mix in, I am keeping it out of my forecasts at this time. Let’s now forget that I even had to mention that.

The front will move out of the area for Wednesday, and temperatures should spring back to or above normal quickly.
