Weather Improves After Tuesday
A meandering area of low pressure has drifted from Lake Erie on Monday to a position directly over the Finger Lakes this morning.
The low, which is cut off from the jet stream and thus moving very slowly, will gradually work its way east today before it dissipates.
With the low directly overhead, most of the Finger Lakes are only seeing a few isolated showers early on this morning. However, there is a wave of energy in the atmosphere rotating around the low.
This will drop more rain showers into the Finger Lakes from the north as the morning continues. By the early afternoon, this rain should swing to the east, leaving us with just a few scattered showers once more.
The scattered showers will continue into the evening, but most of the time it will not be actively raining.
Like yesterday, high temperatures today will be significantly below normal. Most areas should be in the mid 40s. Slightly warmer temperatures will be possible along and north of I-90 while Rochester and points west make a run at 50 degrees.
Skies will remain mostly cloudy overnight which should keep temperatures around 40 degrees for most of the immediate Finger Lakes area. A few of the typically colder valley locations in Central New York and the western Southern Tier could be cold enough for some frost though.
Warmer, but not Totally Dry
The weather will finally start to improve on Wednesday, but it will not yet be a perfect day as a new, small weather system passes across southern Canada.
A brief shower may be possible early in the morning, but the better chance for rain will come in the late afternoon and evening. Scattered showers and a few thunderstorms are expected to develop and drop southeast across the area after 4 pm. Most areas should see at least some rain between 4 PM and midnight, but there should be plenty of dry time as well.
Some sun poking through the clouds out ahead of this rain will help temperatures rise into the low and mid 60s Wednesday afternoon. Temperatures overnight will stick near 50 degrees most of the night before slipping into the mid and upper 40s near dawn.
Thursday looks like a dry day with a mix of sun and clouds and a gentle northwest wind. High temperatures will top out around 60 degrees.
Rain showers will return Thursday night into at least Friday morning. An afternoon downpour or light thunderstorm may pop up across the Southern Tier. High temperatures will be in the upper 60s to near 70 degrees.
The weekend is looking dry with quite a bit of sunshine. Temperatures will be a touch below normal though, with highs in the upper 50s Saturday and low to mid 60s Sunday. Average highs, for reference, are in the upper 60s by this weekend.
