Below Average Temperatures Continue

Our week will get off to a sunny, quiet start, but temperatures will remain below the seasonal averages.

A small bubble of high pressure will control our weather for today. A thin layer of clouds this morning, mainly over the eastern half of the region, will filter some of the sunshine, but that should be it for clouds today.

The afternoon hours will be bright and sunny with no precipitation and few if any clouds.

Gentle north winds will keep temperatures cooler today than it was yesterday.  Highs will range from the low 50s near the Pennsylvania state line, to the mid and upper 40s for the rest of the region. Right along the shore of Lake Ontario, highs will be in the low 40s.

Temperatures will quickly fall into the 30s this evening but will rise again after midnight as a weather system approaches. Low 40s are likely before and just after dawn Tuesday, followed by a late morning drop into the upper 30s.

The temperature drop will be caused by a cold front that will spread rain and a few snowflakes through the area Tuesday morning. Most of the day will end up showery. Afternoon temperatures should bounce back above 40 for a time.

A bit of lake effect snow will be possible Tuesday night into early Wednesday on the northwest winds behind the front. Widespread 20s are expected for lows Wednesday morning. Highs should reach near or just above 40 degrees with increasing amounts of sunshine.

Late Week Weather

The weather for the second half of the week is less certain as a weather system tracks through the Mid-Atlantic region.

Clouds and a few showers may make their way into our area for Thursday, especially over the southern half of the region.

If it is a cloudy, showery day, highs will again be in the low 40s. However, for the areas that do not see rain, and instead see a little sun, low 50s will be possible.

Friday has a better chance for being dry and sunny. Temperatures should return to the 50s for all areas except the shore of Lake Ontario. The Southern Tier will likely be warmest, with highs in the mid or even upper 50s.

Another system will swing by over the weekend. Like Thursday’s system, the path is uncertain at this point and a variety of scenarios are possible.

It may end up cool and rainy with a small chance for a little snow mixing in. Or, the system could be delayed until early next week, which would mean a warmer weekend.

The system may also pass us by completely, with temperatures staying in the 50s. Stay tuned.
