Just in time for Spring the rain showers will help awaken numerous slumbering plants as the temperatures warm. This is the time of year when we start to notice a greener hue on the landscape as well as some buds growing into blossoms on local trees and shrubs. It is a lovely time of year, but when Spring is upon us, the need for water is in high demand to assist in the advent of the growing season. Fog in some spots will also be a strong possibility, especially near waterways and in low lying regions.
Expect periods of rain each day this week to help get Spring off to a good start. A round of heavy rain may cause some flooding issues after midnight Wednesday into Thursday, so we need to be ready for more rain during an overnight time period.
Currently, the forecasting nemesis to the Commonwealth known as Cold Air Damming or “the wedge” is in place and should keep the region cool on Wednesday. Expect cloudy skies, a spotty patch of light rain and drizzle and cooler conditions. Overnight Wednesday into Thursday there is a good chance for some heavy rain to migrate into the area from the West. There may be as much as 1″ of rain measured in some locations from Midnight to 8am Thursday. There may be some minor flooding or even some flash flooding in some spots near sunrise Thursday.
The wedge will get scoured out on Thursday and the temps will rise well above our normal high of 59° and breach the 70° mark. The warmth will also allow some spotty storms to develop in the afternoon, but we should mainly see showers. Friday may bring with it a better chance to hear the rumble of thunder as the temps will approach the 80° mark east of the foothills and more rain is on the way. This line of showers will be associated with a cold front that will drape across the region and push from northwest to southeast in the afternoon. Storms may ignite along the line as we transition from the 80s to the 50s.
Over the weekend we have the opportunity once again of dealing with the cold air wedge. Temps on Saturday will be around normal after a cold front passes in the pre-dawn hours. Then the wedge sets up Sunday and temps will be in the low 50s. The next batch of rain will arrive on Monday, but with the cold air in place at the surface there may be some snow and sleet arriving here before the rain takes over. That is a large forecasting challenge this far out, so we will cross that bridge when we get to it.
As for the Vernal Equinox:
Spring begins on the 19th this year as the vernal equinox occurs at 11:49 pm. According to the Farmers Almanac, this is the earliest equinox in over 100 years. The last time the equinox was on the 19th of March was 1896.
