PITTSBURGH (KDKA) – Showers finally arrived Tuesday night with 0.04″ of rain recorded Tuesday at the Pittsburgh airport. There’s a chance of “light rain and even a little snow in the background” tonight during the overnight hours.
Immediately: We’re back to above average weather after being just a little below average yesterday. Today’s peak will be in the mid-50s with little chance of rain.

Awareness: GFS will see rain Monday through Tuesday with parts of the area likely to rain more than 2 inches. EURO hasn’t come to the party yet but the total number of downpours is still around 0.75″.
The timing of tonight’s rainfall matches well with what we saw yesterday as you can see it slip through at what time of day.
Basically, if you saw rain in your regular day yesterday, you will see rain today.
Total precipitation should be less than 0.05” with most seeing only a small amount of snow. Measurable snow is expected in the Laurels and Ridges but it’s unlikely you’ll see more than an inch.
Considering only today’s forecast with no precipitation, we start with some patchy fog. The fog gave way to a mostly sunny sky.

Today’s high should be back in the mid-50s. Yesterday we hit an intraday high of 58. Normally, given the way the days are set up with momentums, you would expect today will be warmer than yesterday. I actually looked for a reason to raise our high to 58 which we hit yesterday but the numbers show we just hit a low of 50. I am splitting the difference and putting it in. we’re in the mid-50s to hit a peak with the same 55° that I forecast yesterday for today.
Yesterday, I also forecast we will hit 55°. The wind will turn off in a southwesterly direction at 5-10 km/h.
Looking forward, tonight’s rainfall will be driven by a cool front that will cause lift. Colder air will roll in on Thursday with an expected peak of just 38 degrees. Low temperatures for the day are likely to be high just before midnight on Friday, with Friday morning lows expected to drop for teenagers.
This will be the coldest of the next seven days with a strong kick-off expected as we head into the weekend. I have Friday’s high of 46 degrees. Both Friday and Saturday will be dry.
I have Saturday’s highs in the mid-60s. A warm front moved late Saturday through Sunday morning bringing a brief shower of rain. I’m also continuing with Sunday’s peak forecast of 70 degrees with a brief dry spell in the middle of the day. More rain comes on Monday.
While there’s still a week to go, I just wanted to be brief about Monday when we could see significant rain for parts of the region. The stalled warm front gives way to an average low, which could bring up to 2 inches of rain for parts of the region in about 36 hours. The tracking of this system is still in the air but it is something we are aware of and tracking.

At worst, this system will cause moderate flooding concerns for our area by mid-next week and we may need to issue a first Weather Warning date before that date.
