With my most sincere regret, I must inform you that springtime takes a significant “time-out” in the days ahead. A change in the weather pattern is coming that side swipes our young spring season with below normal temperatures, frequent rain chances, and maybe even some weekend wintry weather. So today’s highs in the 60s with intermittent periods of sun should not be taken lightly as it may be quite a while before we see that again.

Today (Tuesday): Weak high pressure drifts by to our north today as a warm front approaches from the southwest. This should allow for some sun at times, especially morning through midday, and temperatures reach up into the low 60s. Light and variable winds combined with intermittent sun allow us to dry out a bit before the next round of rain arrives. Confidence: Medium-High

Tonight: Cloudy with rain returning late at night. Lows in the 40s with light winds from the east. Rainfall could reach up to locally a quarter inch. Confidence: Medium

Tomorrow (Wednesday): This is probably the trickiest day of the work week as low pressure approaches, and the day could be quite variable. Our best bet right now is to expect showers from the a.m. rush through the morning hours. Temperatures creep from the 40s into the 50s. Skies become more variable in the afternoon, and a quick push of warmer winds bring highs to the upper 50s or even low-to-mid 60s briefly. Scattered showers probably return toward late afternoon into the evening rush. Confidence: Low-Medium

Tomorrow night: Expect more showers, especially earlier in the night up to around midnight or so. Colder weather begins to drain into our area as winds start arriving from the north. Low temperatures fall into the 40s under continued cloudy skies. Confidence: Medium


Thursday offers some scattered rain showers, especially in the morning. There is an outside chance for some snowflakes mixing in at times, especially in the far northern ‘burbs. Mostly cloudy skies prevail with highs only in the 40s to around 50 with light breezes from the north. Thursday night sees partial clearing and colder temperatures with lows dropping into the low-to-mid 30s (yes, some areas dip below the freezing mark). Confidence: Medium

Friday is aiming for mostly sunny skies, but a very impressive Canadian air mass is visiting our area, so the late March sun will fight as hard as it can to warm temperatures. We should be able to achieve upper 40s to low 50s, but breezes from the north make it feel not-so-spring-like. Friday night sees more 30s for lows under partly cloudy skies. Confidence: Medium

The weekend is an unfortunate story for spring-seekers. But, at least it looks like you marathon-runners should get a dry morning on Saturday despite cold conditions (30s and then 40s). There is a slight chance of an afternoon shower. Look for partly cloudy skies with highs reaching the upper 40s to around 50 at the most (for reference, our normal high should be around 60 now). Low pressure approaches the area Saturday night into Sunday morning and this is where things get tricky again. Most of it looks like rain, but we could see either mixed precipitation or wet snow by early Sunday morning before the precip ends. It is too early to guess about accumulations. Lows in the 30s Saturday night and highs only in the 40s with cloudy skies on Sunday. Confidence:Low
