Depending on where you live, it’s been either rainy (frequent showers/storms) and cool, or cloudy and warm (with isolated, brief shower activity). The dividing line has been a warm front in the vicinity of central Maryland. To the north, temps have held in the 50s to low 60s, and to the south, it’s been in the mid-60s to near 70. As the front lifts north, everyone gets a taste of warmth tomorrow, before a cold front brings another round of showers and thunderstorms late in the day, which could be strong.
Through Tonight: Showers and thunderstorms which had covered most of central Maryland and occasionally dipped into the District and northern Virginia pull away. So much of the evening is dry and mild, as warm air flows up from the south. Under partly to mostly cloudy skies, overnight lows are 55-60 (suburbs-city).
Tomorrow (Wednesday): Could it be the warmest day of 2011? Quite possibly. A big push of warm air from the south gives rise to afternoon temperatures in the mid-80s, with some isolated upper 80s possible. Late in the day, a strong cold front moves into region, setting off the chance (40-50%) of showers and thunderstorms. A few of these storms may produce damaging winds and hail. We’ll provide more details on the severe weather threat tomorrow morning.
Midwest storms: Another severe weather outbreak may well be initiating in the Midwest. Tornado watches stretch from northeast Texas into central Illinois where storms are just starting to develop.
