Sunday PM Forecast: Enjoy one more pleasant day, a heavy rain threat lurks
Enjoy one final day with sunshine, warmth, and low humidity. Multiple rounds of showers and storms return for the rest of the week. Flash flooding will be a consideration with this stretch of active weather—that is the next impact.
Tonight & Tomorrow: A pleasantly warm evening will turn cool and crisp overnight. Look for a wake-up temperature in the low to mid-50s across the Capital Area. Consider taking a light jacket for the morning commute. But with mainly sunny skies, temperatures will warm rapidly. Highs will climb into the lower and middle 80s, right on track with early May averages. The humidity will also remain low. Take advantage of the beautiful weather—it won’t last!
Up Next: Rapid changes will take place on Monday night as a warm front slides through the region. Clouds will increase through the night, with isolated showers and storms possible by daybreak. The all-too-familiar humidity will also make a return as early as Tuesday morning. And with a front in the area, numerous showers and thunderstorms will be possible through the day. Confidence is growing for an organized complex of thunderstorms to roll through late Tuesday, into Wednesday morning. Most would see rain from this. Intense rain rates could lead to a few inches of rainfall in a short period in spots, so flash flooding is a concern with this round. Those commuting on Wednesday morning might need to look out for areas of standing water. Severe weather is not off the table either, with gusty winds and isolated tornadoes being the primary concerns.
What happens on Tuesday night will set the stage for Wednesday. This introduces some uncertainty at that point in the forecast. Nevertheless, leftover moisture and additional disturbances will keep rain chances elevated. The same goes for Thursday. Any extra rain would aggravate the flash flood risk further. All told, 3-6” of rain with locally higher amounts appears likely in the next week. Most of that will fall into the Tuesday to Thursday timeframe. Moisture will begin exiting around Mother’s Day Weekend. While a spotty shower cannot be ruled out, the upcoming weekend appears relatively drier.
