End in Sight for Odd Southeastern Weather Pattern?

It seems to be the phrase of the season…”what’s up with this weather?” Well, its definitely been an odd spring, to say the least. NC State Climatologist Dr. Ryan Boyles says not only has the past two months been unusually cool and wet:

“The other interesting aspect is that we have one big event that rolls through about once a week. At some point we will move into spring.”
 

Part of what’s creating the current cool, wet weather pattern is the jet stream isn’t where it usually is this time of year, plus high pressure ridges explains Boyles:
 

“We are seeing a lot of high pressure systems moving in and they are bringing in cold air from Canada. We don’t see as much southernly flow as we normally do. We will continue to see cold fronts coming in through June and with them cooler and drier air. These long wave patterns that set up are allowing us to have these few big storm events that come though about once a week.”
 

While the cool, wet weather has been something of a nuisance, Boyles explains there’s been some benefits, as well:
 

“We have seen some pests that have been reduced but with the wet conditions that does increase the chances for fungal conditions.”
 

Boyles explains why, with all this rain, more than 60 percent of the state remains abnormally dry according to USDA’s Drought Monitor:
 

“These are long term impacts that we are seeing largely in our stream flows. The flows have not been recovering. When we only get one event, most of what falls goes to run off. We are not building up that storage capacity in our water tables. A half inch per week is below normal, compared to a normal one inch that we need to get to build and maintain the water table.”
 

So, when we expect Spring to return?
 

“As we get further into the year, we will see more influence from the Bermuda high and more southerly flow and the Jet Stream will retreat farther north.”
