Zany Weather? Wouldn’t You Say?May 7th, 2013 at 8:38 am by Jeremy Wheeler under Weather
I’d say the weather has been at least a little zany lately. We’ve had a weird weather pattern for several days. Up through last weekend we had onshore winds as an area of high pressure sat over the northwest Atlantic and kept up the persistently cool winds. Now this week we have a large upper level low that is drifting towards us from the central U.S. Like yesterday it is pulling in moisture from the southeast. This gave us scattered rain showers with a few thunderstorms this morning.
Now let me back up for a second….Yesterday it looked like the onshore winds were going to keep things cool and cloudy, but I think some of the warm air actually came up, rounded the bend, and moved in from the Atlantic. So that is why we had some clearing. When you get warmer air in place, then that is more conducive to scattered cumulus clouds as opposed to stratus. So the sun popped out and heated us up even more. Instability brought the clouds back in late in the day. Highs were in the 70s. Today after starting with clouds and scattered showers, the sun will pop out (like yesterday) and heat us up once again. Highs will be in the low/mid 70 with some light-moderate humidity. I bet we’ll have some upper 70s inland. Skies will go between partly to mostly cloudy skies through the afternoon. We’ll also redevelop some scattered showers and storms later today. I have the chance for rain at 30% for that time.
Tomorrow the low will move over us, but it will weaken. We’ll have more clouds in the region with another round of scattered showers and storms. The chance for rain tomorrow is 50%. By Thursday the rain should start tapering off. We could see the rain end by the afternoon as the system weakens and pushes out. For now we are looking at a dry and warm Friday. Highs will be in the low 80s.
So far we have picked up about a quarter to a half inch of rain, but some areas have had up to 0.8″ like Barry (my weather watcher) in Gloucester. We expect about another quarter to half inch of rain with the scattered showers today and tomorrow.
We’ll have some more showers and storms late Saturday into Sunday. This will be out ahead of a powerful cold front. Behind the front the 540 line is expected to drop down as far south as Virginia. That is the thickness line that we use to forecast snow in the Winter. No! It won’t snow here as the air will modify under the Spring sun. But we will see a big albeit brief cool down early next week.
