Ahead of the Cold Front
Monday will be another hot and humid day out ahead of a cold front that will move through during the late overnight hours tonight.
West and southwest winds will continue to pump warm, humid air into the region. Already at 8 am this morning, some places are pushing close to 80 degrees.
Temperatures will push into the low 90s for many areas. The humidity will send the heat index several degrees higher, which has prompted the National Weather Service to issue Heat Advisories for all the Finger Lakes Weather counties except Genesee, Wyoming, and Allegany.
By the mid-afternoon hours, a few scattered thunderstorms will pop-up. These will be possible anywhere in the region but may especially be favored along the Lake Ontario lake breeze north of I-90. A secondary favored area could be in the higher elevations across the southern half of the region.
The thunderstorms will stay scattered and relatively small in size. Still, some gusty winds and heavy rain will be possible with any storms. Over half of the region will probably end up rain-free during the daytime hours.
There will be a better chance for some widespread rain and thunder late tonight as the cold front moves through. This is most likely after 3 AM but should mostly be out of the region by 7 or 8 AM Tuesday.
Before this rain moves in, temperatures throughout the night will remain in the 70s.
With the front clearing the region around dawn tomorrow, the rest of the day will be set up pleasantly.
Sunshine will mix with clouds as a gentle, refreshing northwest breeze blows.
Dewpoints will drop into the 50s tomorrow for a very noticeable drop in humidity. Temperatures will still be mild, reaching highs in the low and mid 80s.
Skies will clear Tuesday night and overnight temperatures will drop into the low and mid 60s.
Wednesday will have a few similarities to today as another cold front approaches. Temperatures will be warm, though not as hot as today. Highs should mostly be in the mid 80s, but a few upper 80s will be possible for Elmira, Ithaca, and Owego.
A few afternoon showers and storms may pop up, but these look ever sparser than today’s activity. The chance for showers will continue into the overnight and Thursday. Even Friday could have a lingering shower.
Temperatures will retreat further with low 80s on Thursday and upper 70s on Friday.
The weekend looks dry as warm air pushes back. Highs Saturday look to be in the low 80s with mid 80s on Sunday.
An early look at next week shows a lack of heat with temperatures instead favoring the 70s to near 80 degrees.
