Next Weather System
As one weather system departs the region, another one is approaching from the southwest today.
Skies are mixed to start the morning between the weather systems. Sun and clouds will gradually be replaced by increasing and thickening cloud cover later this morning and into the afternoon hours.
However, the extra bits of sunshine this morning have nudged the expected temperatures up today. Many areas are now expected to top out around 70 degrees by the early afternoon hours.
A band of stray showers will move into the region from the southwest during the late afternoon. Not all areas will see this rain, and those that do should see minimal amounts and a short duration. There is still some uncertainty on whether this band will move through at all before sunset.
The chances for rain will increase this evening with widespread showers. A stray thunderstorm early on cannot be ruled out, which could lead to some brief heavier downpours.
For the most part, the heaviest rain is expected along and north of the Thruway. Locally an inch could fall in these places, where the rain is expected to be more persistent. Further south, amounts will vary greatly with more intermittent rainfall.
South winds will remain light during the daytime hours but will begin to increase this evening. Wind speeds of 10-15 mph are likely with gusts over higher elevations possibly exceeding 30 mph. Winds will be lighter along and north of the Thruway.
Nighttime temperatures will remain in the upper 40s and low 50s, with the warmer air to the northwest and cooler air to the southeast.
There may be a relative lull in the precipitation during the hours leading up to and just after dawn on Wednesday as the center of low pressure passes overhead. Rain showers will become widespread again during the second half of the morning immediately behind the low, with gradually lessening chances for rain in the afternoon.
Temperatures on Wednesday will peak during the early afternoon. Many areas will be in the low to perhaps mid 60s. This time, the warmest air will be in the southeast, while cooler air will begin working in from the northwest. Through the afternoon, temperatures will drop into the 50s, though areas such as Ithaca and Elmira may hold on to 60s until late in the day.
Thursday will be a quiet day in the weather, once again between two systems. Skies will have some sunshine, especially early in the day. Clouds will be moving in, though these should mostly be thin clouds that still allow at least partial sunshine through.
Light north winds will blow throughout Thursday, keeping temperatures in check. After starting in the low 40s, afternoon highs will top out in the low 60s.
High pressure will move through Thursday night, setting up a southeasterly flow between the high and a slowly approaching frontal boundary on Friday. If rain arrives on Friday, it should do so from southwest to northeast later in the afternoon. This remains uncertain, though.
Temperatures on Friday may depend on how the cloud cover and rain evolve, but highs will be in the same general neighborhood of the 60s.
Rain will become increasingly likely Friday night and into Saturday. Again, there is still uncertainty here, but most models agree that rain is more likely on Saturday. Temperatures will be held down by the rainy conditions, possibly even struggling to reach the 50s.
Another stretch of dry, sunny, and warm conditions is expected next week. Temperatures may really take off, with 70s highly likely and a few days of 80s not out of the question. Dry air should prevent pop-up showers and thunderstorms, at least until late next week at a minimum.
