The far eastern reaches of the Finger Lakes may see showers and storms develop overhear before quickly moving east.
For the vast majority of the Finger Lakes, Tuesday will be mostly dry with a mix of sun and clouds. A cold front will cross the region during the morning and early afternoon hours. Nothing more than a stray shower is expected until the early afternoon.
Between about 1-3pm, showers and storms will start to initiate. There is a narrow window of opportunity for Tompkins and Cayuga county to see some rain as the rain first develops. It is uncertain, however, whether anything substantial will develop over these counties before the front pushes activity to the east. Cortland and Onondaga county will have a slightly higher chance for seeing some rain, but again, it is uncertain how much development will occur.
Should development occur quick enough, areas near I-81 could see a stronger storm pop up. Showers and thunderstorms will continue to develop and intensify as they move east of the Finger Lakes. While eastern New York and eastern Pennsylvania may see some beneficial rain, along with some severe weather, it will remain dry across the Finger Lakes.
Temperatures today will range from the upper 70s to the low 80s, with highs occurring early in the afternoon. Skies will remain cloudy overnight with a stray shower or two. The threat for a spit of rain will persist into Wednesday morning, but high pressure will build in later in the day, resulting in some late day sunshine. Highs will mostly be in the low and mid 70s. Wednesday night will turn chilly, with many areas in the low 50s.
Warmer weather will try to sneak back in for Thursday and especially Friday. Highs will be in the low 80s Thursday with some mid 80s Friday. A few late day showers Friday will signal another cold front. This front will set the stage for a rather nice 4th of July weekend, with sunny skies and highs comfortably in the 70s. However, it could be a week or more until our next chance for beneficial rainfall.
