As we say goodbye to our latest arctic fling with highs in the 20s the last two days, we’ll welcome in a quick rebound in temps for our NW Indiana Sunday.

A dome of warm air will move in out ahead of a carving trough of low pressure in the western US. The result will be high temps that surge back into the 50s with increasing clouds.

If we look into the weather crystal ball of the next 10-15 days, the pattern will flip back to what we’ve seen for much of the winter season. A trough out west and a ridge cutting across the Ohio Valley–bringing the storm track and heavier rains to the Tennessee Valley and southeastern US and leaving us with more milder days than cold.

See how the jetstream changes? The arctic gets “shut off” once again and we tap into a zonal flow (from west to east across the US) and even briefly tap into southwestern (real warm stuff!) flow for a few days:

We’ll likely see a few periods of warmer days mixed with several very brief cold days. Let’s chat numbers during our milder spells…

Here’s a look at Sunday. Notice the warm airmass we’re tapping into with widespread 50s and 60s as far as the eye can see!

After a cooler day Monday with wind off the cold lake, we look to rebound quickly once again with a fairly mild week beyond Monday. Out ahead of another front Thursday our temps could spike into the upper 50s to near the 60 you see here:

After another brief cool shot Friday, more spring-like air builds in the plains setting the stage for another mild spell next week with warmth building as far north as Minnesota–a good sign that it shows up here a day or two later. This is next Monday:

Either way, Sunday begins “Meteorological Spring”–when our sun’s energy ramps up the fastest bringing us brighter days, longer days, and more frequent periods of spring-like warmth.
