A persistently unsettled pattern will result in some showers on Tuesday and perhaps some thunderstorms Wednesday and Thursday.
The storm system that brought the rain to the area on Monday is now heading well out to sea south of New England. In its wake, however, is another small area of low pressure.
This low will slowly track from eastern Ohio across the Finger Lakes and into northern New York today. At least a few showers will spread across the Finger Lakes with a chance for a slow moving, more widespread rain this afternoon. The further east you are, the less of a chance there is of some steady rain, but it remains at least possible for all of the Finger Lakes.
That system will clear out by the late afternoon or evening hours. After highs in the upper 40s, overnight lows will fall back to near 40. Southerly winds will start to push warmer air in for Wednesday. By the afternoon, many areas may be pushing towards 60 degrees,
Along with the push of warmer air will be another chance for rain in the afternoon. This time, the rain will likely be accompanied by at least a couple rumbles of thunder, if not some legitimate thunderstorms. At most, some gusty winds and small hail may be possible if everything comes together just right.
On Thursday, the Finger Lakes will remain on the warm side of a developing front across southern Canada. More showers and even thunderstorms are possible on Thursday, though the exact evolution of the weather during the afternoon is just a touch uncertain. Temperatures should be in the 50s.
Cold air will stream in on Friday as the front sags south. Temperatures will fall through the 30s. Rain and snow showers will again be possible.
The sun should finally return on Saturday, but it will be chilly with highs in the low 30s. Sunday and Monday are very uncertain at this time, and it is definitely far from certain that there will be a storm.
