Active Weather Continues

A stalled out frontal boundary will serve as a pathway for more rain in the Finger Lakes.

Showers are scattered about the region this morning as a weak area of low pressure rides along the front.

These showers are generally contained to areas south of I-90, but even the northern areas could see a bit of rain this morning. None of the rain will be heavy.

Rain will exit to the east by the midday hours, leading to a dry afternoon and evening between weather systems. Clouds will remain in place early, but sunshine should become more plentiful late in the day.

With the front nearly overhead, winds will be lighter today with top gusts under 20 mph. These winds will be from the northwest and north.

High temperatures today will approach 70 degrees in the Southern Tier while areas north of I-90 mostly stick in the upper 50s. Low and mid 60s will be sandwiched in between for the remainder of the Finger Lakes.

Clouds will increase overnight as a new low pressure tracks northeast along the front. Morning temperatures on Friday will be in the mid 40s.

Showers and possibly a rumble of thunder are likely Friday morning before a lull in the activity during the early afternoon. Temperatures will jump into the mid and upper 60s at this time, especially if some sun can sneak out.

A cold front will move through during the late afternoon. A small line of thunderstorms should develop along the front and move through the Finger Lakes between 2-5 pm. This line will have some downpours, a few claps of thunder, and perhaps a slight increase in the wind. Severe weather is not expected.

As has often been the case this spring, once the line of storms moves through, temperatures will take a dive from the 60s to the 40s by Friday evening.

Weekend Outlook

By the start of Saturday morning, the frontal boundary will be well to our south, stretching from Arkansas, where a new low pressure will be forming, into the Mid-Atlantic. A weak high pressure will be crossing the Great Lakes.

Out ahead of this high pressure, a small pocket of moisture will bring some clouds and a couple morning showers to the Finger Lakes on Saturday. This rain will be very light and many areas will probably remain mostly dry.

Some sun will try to push through the clouds on Saturday, but as the thick, low level clouds burn off, thin clouds high in the atmosphere will move in.

The limited sunshine combined with a gentle north wind will keep temperatures in the upper 50s to near 60 degrees Saturday.

The low pressure that will be over Arkansas Saturday morning will be moving into southern Pennsylvania by Sunday morning. Some steady rain from this system should make it into the Southern Tier and Central New York Sunday with a few showers further to the north and west. The rain is most likely during the morning hours with just a few lingering showers in the afternoon.

Sunday’s temperatures will be warmest to the north and west where mid and upper 60s are possible along and north of I-90. Temperatures will drop through the 60s the further south and east you go with upper 50s possible southeast of Ithaca.
