FORECAST IN DETAIL

As inconsistent as the weather has been this spring, it is trending warmer. Whereas over the last couple of weeks we saw several days with highs stuck in the 50s, none of that this week. But we do continue the maddening pattern of showers/storms every two or three days, including once again this Saturday. We will fit in the occasional pleasant day in between, starting with today.

Today (Monday): A great start to the week with no weather worries for last minute trips to the post office for the many proscrastinating tax filers. A stalled out front should stay far enough to the north to allow sun at times. That, along with a breeze from the south (at 10-15 mph), send afternoon temps up to near 70. Confidence: Medium-High

Tonight: Clouds increase as a disturbance riding along the front to our north approaches (from the west). The blanket of clouds holds up overnight temperatures, with lows 50-55. Confidence: Medium-High

Tomorrow (Tuesday): Exactly how far north of us the front lies will determine how much cloud cover and shower and thunderstorm activity we see. I think we’ll see some (especially the northern suburbs), with the best chance of any activity during the afternoon and evening (60% chance), but some showers aren’t out of the question (30% chance) in the morning either. With the front likely remaining to our north and a good chance of some intervals of sunshine, mild flow from the south should push temps up to near 70 (but areas north of town will probably be cooler). Confidence: Medium

Tomorrow night: Evening showers and t’storms are possible (30-40% chance), followed by mostly cloudy skies. It’s quite mild, with lows 55-60 (suburbs-city). Confidence: Medium-High

A LOOK AHEAD

Strong flow from the south Wednesday makes for a potentially very warm day. Highs could surge into the mid-80s or so. Late in the day and at night, a fairly strong cold front cuts through the region, likely triggering another round of showers and thunderstorms. Some of these storms may be severe. It begins to clear late Wednesday night with lows in the 50s. Confidence: Medium-High

For the most part, Thursday and Friday look pretty nice as high pressure builds into the region. It’s cooler but mostly sunny behind the cold front Thursday, with highs 65-70. That’s still slightly warmer than average. Clear and seasonable Thursday night, with lows in the 40s. On Friday, winds may become more from the east, cooling it down a shade and increasing clouds a bit. On the other hand, last Friday flow from the east did not stop it from being a really nice day. We’ll call it partly sunny, with highs in the mid-60s. Could see a shower Friday night (low chance) as a warm front pushes through; otherwise, it’s partly cloudy with lows 50-55. Confidence: Medium

Details are fuzzy, but once again we see the threat of showers and thunderstorms next Saturday. At this point (and details may well change), they do not appear to be as long in duration, widespread or severe as last Saturday. They should be more confined to late afternoon and evening time period. Nonetheless, there could be a few strong ones. Southerly flow ahead of the approaching front may warm us up well into the 70s. Showers and storms end early Saturday night, allowing for gradual clearing. Right now, Sunday looks good, with morning lows around 50 and afternoon highs around 70, with partly sunny skies (but if the front slows down and stalls, it could be cloudy, cooler and even wet). Confidence: Low-Medium
