Pattern change in progress moving bone dry start to Fall into more rainfall… But just remember it “could” be snow

Warm temperatures will be making a comeback over the next couple days after we cooled down to near average temperatures the last couple days.

This warm up is due to our area being sandwiched in-between a high pressure exiting the area to the east and a low pressure system approaching from the west.

With winds flowing clockwise around high pressures, and counterclockwise around low pressures, that puts us in the perfect location for southerly winds to advect into the area bringing in warmer air.

We’ll see highs in the mid 60s today and then warming to the mid 70s Friday and around 70 on Saturday.

Unfortunately however, we need to also deal with an increase of rain in the area as this would be a byproduct of both southerly winds bringing moisture north from the gulf, and that low pressure moving in which promotes rising air. When warm moist air rises into cooler air aloft, the moister condenses, forming clouds and eventually precipitation.

Right now models show just the smallest of chances for a scattered sprinkle tonight, but a much better chance of a line of showers associated with a weak cold front moving over the area Friday night.

In between, Friday during the day looks to stay dry, though those southerly winds could really ramp up as this low pressure is intensifying.

Normally after a cold front passes, the rain stops as cooler dryer air moves in, however this wont be the case this time as another low pressure forms just south of us Saturday, bringing more showers into the area Saturday afternoon through Sunday afternoon.

Right now models have this second low being a fairly prolific rain producer, with the Fond du Lac area being just on the outer edge of the heavy rainfall. If the low were to move even just slightly farther north than what models say, we could be in for a soaker for the later half of the weekend. Models are hinting at over an inch for areas just to our south east like Washington County as of now.

Then we get a chance to dry out Sunday night and Monday as a high passes to our south. But another low pressure storm passing to our north will reintroduce a chance of rain as well as some cooler temperatures for the middle of next week.
