Discussion

A frontal system has stalled just south of here at the same time high pressure is building into New England. While today should stay on the dry side, the threat for showers and thunderstorms will return on Saturday and continue right into early next week as the frontal system hangs around the region. The clouds will help to create cooler conditions this weekend with high temperatures on both weekend days not far from 70 degrees which is below normal for this time of year. Winds will become southwesterly by Tuesday and this change will usher in a warm and more humid air mass by the middle of next week.

Discussion

A frontal system passed through the region yesterday and has stalled out near the area at the same time high pressure builds across New England. This stalled out frontal system will keep things unsettled over the next couple of days with the constant threat for showers and thunderstorms although much of the time will be rain-free. One band of showers is dropping southeast from southern Pennsylvania this morning and it is likely to move across the DC region during the mid-day and afternoon hours. It’ll turn slightly cooler over the weekend as the New England high pressure influences the region and the threat for showers and thunderstorms will continue.

Discussion

Milder air will push into the region today, but it'll be accompanied by mostly cloudy skies and the threat for a shower or thunderstorm at just about any time. Weak high pressure takes over for the last couple days of the work week, but a shower or thunderstorm cannot be ruled out either day as temperatures climb to or slightly past the 80 degree mark. A low pressure area will move to the east this weekend and enhance our chances for showers and thunderstorms and bring us slightly cooler conditions.

An update on the sun - there has been a fourth "X-class" solar flare from the very active sunspot region called AR1748 that occurred earlier today. Before the week began, the sun had not unleashed any X-class flares, but now there have been four in just the past few days.
