Forecast: Cooler Air Almost There
We are just hours away from what should be our last 90-degree readings of this week. Believe it or not, after what will be seven straight days above the 90-degree threshold, we are finally seeing the end to this July heat wave and introducing a period of relatively cooler and more frequently wet weather conditions. The change catalyst this time is an upper level low pressure area swinging southeastward through the Great Lakes and headed very slowly this way. The first signs of this rainmaker arrive this evening with more clouds and evening thunderstorm opportunities.
Hot and humid with one last push into the 90s. Evening thunderstorms too. The upper level low will slowly shift toward the area and introduce more cloud cover by afternoon. Temperatures should still jettison toward the middle 90s in the city and low-to-mid 90s in the suburbs. Also, look out for a 30% chance of scattered thunderstorms towards the evening hours.
More clouds than moon tonight with a healthy 50% likelihood of thunderstorms. Some weather models suggest storms even past midnight around the DC metro area. Lows in the lower 70s.
Keep reading for the forecast through the weekend. See UnitedCast for the outlook for tonight's game.
A Rainy Day? Showers and storms with highs in the middle 80s. Frequent opportunities for showers and thunderstorms are seen on Wednesday here with a fairly consistent cloud canopy overhead and high temperatures struggling to reach the middle 80s throughout the area. If heavier rains abound at midday, our high temperatures may be cooler than forecast.
More showers and storms are anticipated Wednesday night with the potential for heavy rainfall totals (perhaps an inch or more especially in the evening hours). Look for lows to drop into the lower 70s in the city and upper 60s in the suburbs.
Thursday and Friday are overall on the drier side, but there may be some scattered showers around on Thursday morning (30% chance). More likely will be shower activity along the beaches off to the east. Highs Thursday, under partly cloudy skies, should be in the more comfortable middle 80s. A bit more sun on Friday should yield upper 80s instead. Lows are in the upper 60s to near 70 again. Confidence: Medium
The weekend (as you would expect) is reintroducing threats for showers and thunderstorms. Right now, the best thinking is for highs in the middle to upper 80s with an around-the-clock 40% likelihood of those showers and storms. Overnight low temperatures should reach down into the upper 60s and lower 70s again. That upper level low should still be mostly dominant this weekend so temperatures should stay below the 90s threshold, but clouds will also be frequent visitors. Confidence: Low
