JAMESTOWN – A weak area of high pressure will give us a dry but mostly cloudy afternoon. A storm system squeaking by to our south will brush us with some early showers Wednesday and Thursday before the weather becomes much more active over the weekend.
While there could be a few peaks of sunshine this afternoon, the clouds will mainly dominate through the day today. With the advent of the cloud cover and a northerly wind, that will hold down our temperatures. Highs 38 near the Lake Erie shoreline to 46 inland.
Mostly cloudy skies will take us through tonight with the chance for a light rain shower towards the morning hours as a storm system passes south of us through Pennsylvania. Lows 33 valleys, 35 lakeshore. Light wind.
We will start Wednesday with a chance for a morning shower then some partial clearing for the afternoon. With a southerly wind setting back up, we will be milder than we have been the past few days. Highs 45 to 53.
The same idea is in play for Thursday. A small chance for a morning rain shower with partly sunny skies in the afternoon and milder. Highs 50 to 57.
We will have one completely dry day come up on Friday which will be out ahead of our next weather maker which will head our direction over the weekend.
Guidance has been consistent is showing a developing storm over the midwest which will then track through the upper Great Lakes over the weekend. There still remains a lot of questions in regard to the exact track the storm will take in relation to Western New York and Northwestern Pennsylvania.
As of this time, we feel the heaviest and steadiest of the rain will be later Saturday morning into Saturday night, turning into scattered showers for Sunday. However, understand that this forecast is subject to change as we are still several days out.
High pressure returns early next week bringing us partly sunny skies for Monday with highs in the mid 40’s.
