After a brief warm-up on Monday for much of the eastern U.S., a cold front is forecast to reach the coast by Tuesday evening and bring a return to slightly cooler conditions for the middle of the week. The cool-down behind this boundary will not be as significant as the last cold front that brought the widespread sub-freezing temperatures for overnight lows. Showers and a few thunderstorms are possible ahead of the front on Tuesday.
Numerous showers and thunderstorms are expected along and ahead of the southern portion of the cold front near the Gulf Coast, especially on Tuesday. Conditions will be favorable for heavy rainfall along with scattered thunderstorms through Tuesday evening, with the best concentration over southern Texas to the Florida panhandle. A few inches of rainfall is possible for some areas, and flooding remains a localized concern. However, less in the way of severe thunderstorm coverage is expected compared to Monday.
Scattered showers and a few thunderstorms are likely from the Pacific Northwest to the central Rockies for the middle of the week, with the greatest rainfall totals expected near the Oregon and Washington coasts as a Pacific storm system makes its way onshore, with snow likely at the highest elevations.
