WASHINGTON (WUSA) --It sure has been a cool March. Looking at the high temperatures at Reagan National, you can really see the difference. Last year we spent a lot of days with above average highs. (The yellow line is the average high which has risen from 51º to 57º from the 1st to the 18th)
This year has been totally different. Most days have been below average. last year we managed to already see low 80s for a few days and the Cherry trees at the Tidal Basin saw peak bloom on March 20.
This year, the cold has forced the National Park Service to adjust their forecast later into the season. Originally, their forecast was for peak bloom between March 26 and March 30. Just this morning, they pushed that forecast back to between April 3 and April 6.
Yes, some varieties of cherry trees have already bloomed, but the Yoshino variety of trees has not. The water itself also tends to keep the area along the Tidal basin a little cooler as well this time of year.
Looking ahead, unseasonably cool weather is likely for the next 1 to 2 weeks and we even have a threat for more wintry on Monday, March 25.
This is the "Euro" (ECMWF) from 7 pm Monday night looking out at the Monday 7 AM period. If this verifies, we would see a mix changing to snow. It's still way too early to tell if this will verify and what sort of storm this would be, but, it has been a chilly month and we'll definitely watch it!
