An area of low pressure just north of Lake Ontario will drag a cold front through the region today with some scattered showers and storms.
Isolated showers that developed yesterday afternoon continued through the night and remain across portions of the region this morning. Most of the rain is brief and light, but there is some lightning and a few heavier bursts as well.
The chances for some isolated rain will continue this morning, but most areas will be dry most of the time. Skies will be cloudy, though some breaks of sun will mix in here and there.
During the midday and early afternoon hours, showers and thunderstorms will increase in coverage, but remain hit or miss with individual cells or a couple small clusters. Only localized downpours and gusty thunderstorm winds are expected. Some areas will end up seeing little to no rain.
The thunderstorms will weaken late this afternoon and showers will mostly dissipate by sunset. A few isolated, stray showers may linger for a few hours after sunset, but these will be brief and sporadic. Skies may briefly clear for a time tonight, but the window for this is narrow. Clouds will thicken during the overnight with spits of rain and drizzle into Saturday morning.
South and southwest winds this morning will gradually turn to the west, then northwest as the front moves through. Wind speeds will be 5-10 mph with non-thunderstorm gusts around 20 mph.
High temperatures this afternoon will mainly be in the upper 70s. If some sun works out a bit more than expected, a few places could reach 80 degrees. Evening temperatures will drop into the mid and low 60s, with overnight lows in the upper 50s to near 60.
There may be some areas of fog tonight, particularly in areas that see rain later in the afternoon or evening. Higher elevation fog may also be possible tomorrow morning with the low clouds and drizzle.
Mostly Dry Pattern Ahead
High pressure will build in from the west Saturday afternoon, gradually clearing out the showers and clouds lingering over the area.
Temperatures on Saturday will be cooler with a light north wind. Look for highs in the low and mid 70s.
By Sunday morning, winds will turn lightly to the southeast. Areas of fog will be possible with lows well down into the 50s. The fog will burn off during the mid-morning hours, leaving a mix of sunshine and small fair weather clouds.
The sunshine and southerly flow will help temperatures jump. Highs will be 10-15 degrees warmer than Saturday, reaching the mid 80s.
Monday will be even warmer and many places will flirt with 90 degrees. One thing that may prevent it from quite reaching 90 will be an increase in afternoon fair weather clouds and a few scattered showers popping up.
The best chance for rain in the next week will come sometime Tuesday or Tuesday night as a cold front moves through. Showers and storms look to be more numerous than today and with more potential for downpours. It remains early, though, so the details can easily still shift.
Temperatures will take another dip later next week with highs retreating to the low 70s by Friday. From there, there will be a slow but steady rebound with highs around or above 80 degrees from Labor Day onward. The chances for rain beyond Tuesday look minimal through the holiday weekend at least.
