Rain Chances

A weak, slow-moving low pressure system will keep our weather on the unsettled side today.

The low is centered over northern Vermont this morning and has a subtle front that extends west through northern New York, across Lake Ontario and Lake Erie, and into the Ohio Valley. This boundary will slowly press southeast through the Finger Lakes today.

Along and ahead of the front, a few showers will be scattered throughout the day. The showers are light and isolated this morning but should increase slightly in coverage and intensity as the day goes on.

At its peak early this afternoon, expect scattered showers and a few small thunderstorms, especially across southern and eastern areas.

There is no specific boundary that is more likely to see rain, but it is a gradual increase in rain chances the further south and east you are. Not everyone, even in those southern and eastern areas, will see rain or storms today.

One or two storms could have some gusty winds or brief downpours. Like yesterday, though, I am not expecting much if any severe weather in our area.

By the mid-afternoon, most of the activity should be pushing south of the region, though a stray lingering shower will continue to be possible into the evening.

High temperatures today will generally be near or just below 80 degrees, though it will remain plenty humid.

Winds will be from the west ahead of the front but will turn to the northwest as the front passes through. Wind speeds will be 5-10 mph.

Warming Up

High pressure will gradually take control of our weather this weekend, leading to increasing temperatures.

Friday will likely start off with some areas of clouds and patchy fog. The morning clouds will burn off and be replaced by fair-weather clouds during the midday and afternoon hours. Precipitation is not expected.

Highs on Friday will be a few degrees warmer than today, topping out near or just above 80 degrees.

Saturday will see a further increase in sunshine and temperatures. Look for highs to be in the mid 80s for most areas with low 80s in the higher elevations.

Winds on both Friday and Saturday will be light with speeds at or below 5 mph. Friday’s winds will be northerly, while Saturday’s will be variable early before turning to the south.

Sunday will be the hottest upcoming day as temperatures break 90 degrees in many areas. Temperatures should not get warmer than the low 90s, though.

Sunshine on Sunday will be filtered by thin clouds out ahead of a front. However, it continues to look safe to say that the daytime hours Sunday will be dry. Winds look to be from the west or southwest at 5-10 mph.

The front may not move into our region until later Monday. If the arrival time is late enough, showers and thunderstorms will have to be expected. Tuesday could also be stormy.
