We’ll find high pressure wedging back into the area on Tuesday as it passes to our north. Morning lows will bottom out in the mid-to-upper 30s across the metro, with mid-30s wind chills possible with the northeasterly wind. (You might want to bring pets and sensitive plants in tonight, just in case.) With little moisture in place, we’ll see mostly sunny skies, but the influx of cooler air will keep highs pinned to the mid-50s despite the sunshine — solid sweater weather if I do say so myself.

Rest of the work week: Turning warm, stormy, and then cooling off for an extended period

High pressure will slip offshore later Tuesday into Wednesday as a potent storm system moves in from the west. This will help temperatures rebound to the mid-60s on Wednesday afternoon. We may see some showers develop later in the day Wednesday as a warm front takes shape to the south, but the better rain chances arrive overnight and into Thursday as the warm front lifts north of the area, placing us in the warm sector. Highs on Thursday will run in the low 70s — perhaps for the last time in a little while — ahead of the front. Showers are a near-certainty from mid-morning through early evening, while a few thunderstorms will be possible as well. It remains to be seen if enough instability can develop, but the shear certainly looks good. We may be too far north for much of a severe threat, though. (Fingers crossed!)

By Friday, the front will have swept offshore, ushering in a much cooler airmass. Highs will top out in the upper 50s at best as cooler air moves into the area. By the weekend, we’ll see highs peaking only in the low-to-mid-50s as a second reinforcing shot of cool air moves by. We look to keep this cool weather in the forecast well into next week, too, with some models showing a rather chilly Christmas ahead (but that is certainly getting ahead of ourselves a little!)
