An evening cold front will drop south through the region today, ushering in another chilly day tomorrow.
Out ahead of the front, however, it will be quite mild this afternoon.
West-southwest winds will blow ahead of the front, increasing through the morning and peaking in the afternoon.
Wind speeds will be around 10 mph across the southern half of the region, and slightly higher than 10 mph across the northern half. Gusts will be near or under 30 mph to the south, and as high as 35 mph to the north.
Warm air will move in on these winds, increasing the temperatures over yesterday. Look for highs mainly in the mid 70s, with the usual topographic variations.
Sunshine will be filtered through thickening clouds over the course of the day. Late in the day, the clouds should be thick enough to limit the sunshine significantly.
As the front drops south, a few isolated showers will move into the region. These will be dissipating as they arrive around sunset, so northern areas will have the best chance of a few drips of rainfall. Even those that do see rain will not see anything significant or meaningful. Most areas will not see anything at all.
Winds will turn to the north with the frontal passage and temperatures will quickly fall into the mid 40s from north to south this evening. By Wednesday morning, temperatures will range from the mid 30s in some of the typically colder valleys to near 40 along the lake shores.
Like Sunday, Wednesday will be deceptively sunny. Few, if any, clouds are expected, but blustery north-northwest winds will blow, keeping temperatures even colder than they were on Sunday. The best chance for wind gusts around or over 30 mph will be from Syracuse to Penn Yan and south and eastward.
High temperatures will struggle into the low 50s on Wednesday. Some higher elevations may get stuck in the upper 40s, while a few of the broad river valleys of the Southern Tier may creep into the mid 50s.
Clear skies and calm winds Wednesday night will lead to widespread frost and freeze conditions. Low and mid 30s will be commonplace, but some colder pockets will probably end up in the 20s. Even typically protected areas may need to be proactive about frost prevention.
The weather will continue to send temperatures up and down in quick, notable swings, though not as dramatic as mid 70s today to low 50s tomorrow.
Thursday will see temperatures jump about 10-15 degrees over Wednesday, despite the cold and frosty start. Look for highs to make it into the mid 60s for most areas.
It will be a sunny day with just a few thin clouds, mostly late in the day. Winds will be nearly calm early, then will become southerly at a gentle 5 mph during the afternoon.
Clouds will increase on Friday, though at least some filtered sunshine is still expected. South winds will increase to over 10 mph with gusts to 30 mph.
Even with the limits on the sunshine, the wind will help temperatures bounce up another 10 degrees or so with highs in the mid 70s.
Saturday has a decent chance for some rain as another weather system moves through the region during the afternoon. This rain looks to be much more substantial than the spits expected tonight, but still not overly heavy. Early estimates are placing rainfall amounts between a quarter and half an inch.
With the anticipated clouds and rain, temperatures will likely be held in the 60s on Saturday. Of course, if the rain holds off until the nighttime hours, temperatures may end up warmer during the day.
Sunday should have plenty of sun with westerly winds. Temperatures will not cool off yet, with highs pushing back towards the 70s. However, by Monday, winds will turn northerly, and highs will retreat back to the 60s once again.
Another mostly dry week may be in store for the area next week with temperatures making a slower but steady upward push with most days near or above 70 degrees.
