Live Weather Updates from CWG’s Twitter Feed.

We’re almost getting used to these highs in the 70s, which is a good thing as averages have now fallen to there. Thanks to plenty of clouds today, afternoon temperatures are running a few degrees below normal, but I doubt there are too many complaints! Clouds should continue to thicken heading into the evening, and showers are also approaching from the south and west.

Through Tonight: It’s mostly cloudy, with an increasing chance of showers. The first push may favor western areas or even west of the area, but as we get toward sunset and beyond there might be a few around. After midnight, periodic showers become likely (60% chance) heading into morning. Lows reach the mid-60s to near 70, and dew points creep up toward the mid-and-upper 60s as well, so it’s going to be feeling muggy.

Tomorrow (Tuesday): A potentially wild day is ahead as a strong cold front brings shower and storm risks (90% chance) off and on through the day. The main focus -- including the largest severe storm potential -- should happen from midday into afternoon and evening. Damaging wind, very heavy rain and isolated tornadoes are all possible. Highs could range anywhere from the mid-70s (rainiest scenario) to the low-80s (if most activity is later in the day). Rainfall totals of 1”+ may be common, with some spots of more and some of less.
