A strong front will extend east towards the Southern Tier today, keeping areas south warm while the Finger Lakes stays cooler.
Temperatures will vary quite a bit across Upstate New York over the next 24 hours, with the warmest readings along and south of the front and cooler air to the north. While not quite as intense a cut off between cold and warm as some of the fronts we see, there still could be a 15 to 20 degree temperature difference across the area.
High temperatures today will reach into the 50s for most of the Finger Lakes, with low 50s closer to Lake Ontario and mid and upper 50s for the remainder of the area. The Southern Tier, however, should reach well into the 60s, with far southwestern New York possibly even pushing 70 degrees.
An area of precipitation is showing up on radar this morning across the region. However, it appears that most of this is not reaching the ground as it falls into dry air. Nothing more than a few drips and drops should be expected today until very late in the daylight hours. This evening, a disturbance will ride along the front, spreading rain into the Finger Lakes.
This rain will continue overnight and into Tuesday morning. It may not rain the entire time, with a lull in the precipitation especially possible early Tuesday just ahead of low pressure. As this low moves into Western New York, a push of warmer air will make a run at the eastern Finger Lakes, and some areas around Ithaca and Cortland could briefly push into the 50s. The remainder of the Finger Lakes should be stuck in the 40s, with the warmest temperatures early in the day.
Colder air will quickly move in as the low crosses the Finger Lakes. Much of the day will see temperatures near 40 degrees. As this cold air pushes in Tuesday morning, there may be some thunderstorms that develop, along with more showers. The precipitation should end by the afternoon, with a little sun possible very late in the day.
The weather will quiet down for the remainder of the week, but it will remain chilly. Wednesday looks sunny, as does Friday. Clouds will be possible on Thursday, but no precipitation is anticipated. Temperatures will become more uniform across the region, with highs near 50 on Wednesday, in the mid 50s Thursday, with upper 50s Friday. Morning lows all three days will be near or below the freezing mark.
At this point, Saturday looks like the nicer day of the upcoming weekend, with temperatures in the low 60s and a mix of sun and clouds. Rain may develop on Sunday, with cooler temperatures. Below normal temperatures will persist into at least the first week of May.
