Hope you enjoyed our second day of temperatures near 70 degrees, as it’s all about over. A strong cold front approaching from the west brings showers overnight and into the morning, along with considerably cooler air. In fact, daytime readings look to be about 20 degrees chillier tomorrow compared to today. And that air mass sticks around for the rest of the week, with only some moderation as we move forward.

Through Tonight: The cold front to our west continues its march toward the area. Showers may begin to break out between about 7 and 10 p.m., primarily over western parts of the area, before the whole region faces that threat through the overnight. Though we stay mild through the evening, colder air filters in behind the front on winds about 10-15 mph from the north and northwest. Lows should make the mid-40s to near 50.

Tomorrow (Tuesday): Showers persist into the early morning behind the front. Some rain should continue to plague the morning rush hour, though it tends to shift east by 10 a.m.-noon or so. Total rainfall of about 0.50” (give or take a tenth or two) is a good bet by the time it ends. Clouds may be slow to clear after the rain finishes, but we should see some sun in the afternoon. Temperatures don’t go too far, mainly hovering or perhaps rising slightly off morning lows, with daytime highs in the upper 40s to low 50s (actual highs probably happen near midnight most spots). Winds continue around 10-15 mph with higher gusts.
