Another mid-week cold front brings rain and cooler weather

Last week, a strong cold front came through, bringing post-frontal rain showers and a blast of cold air that dropped temperatures to their lowest level of the fall and widespread frost outside the city limits. This week, another autumn cold front arrives in a similar fashion. Once again, we'll see scattered showers ahead of the front (very little in the way of thunder is anticipated), post-frontal rain, and falling temperatures. The main difference between the two systems is that I don't anticipate temperatures to drop as low as they did last week.

The first showers should move into the area overnight Wednesday night with the cold front arriving in the wee hours Thursday morning. Wednesday night's low and Thursday's high will both be in the upper 50s with temperatures likely to slowly fall with the rain during the day Thursday, dropping to near 50 by the afternoon rush hour.  By Friday morning, rain will be ending and the low will be in the mid 40s. Clouds depart Friday with highs only in the upper 50s.  Saturday and Sunday mornings will be quite cool, though widespread frost in the suburbs is not expected (though frost is possible in the coldest outlying areas). Rainfall amounts with this system should average about an inch in most locations. See the MWN Forecast for the latest information and what to expect for your ghouls and goblins on trick-or-treat night!

This weather system will also be responsible for the first good snowfall of the season for much of the interior Northeast U.S. and New England, following on the heels of the first snow (some of it heavy) for the central Rockies and Front Range, including Denver and Colorado Springs, on Wednesday.
