THE WEEKEND MAY BE A BIT UNSETTLED, BUT IT SHOULDN’T BE TOO BAD… IT’S A DIFFICULT FORECAST FOR THE NEXT FEW DAYS

The combination of a slow moving upper-level low pressure system, ample moisture,  and an onshore flow will make for a difficult forecast through the weekend. Further complicating the weather picture is the possibility of a low pressure system developing well to our southeast over the ocean, which may actually move towards the coastal Carolinas. Although this cyclone is not expected to be tropical in nature, it may aquire sub-tropical characteristics. One model is very aggressive with this system while most others don’t intensify it quite as much. Either way, forecasters will be keeping an eye on it. The Atlantic hurricane season is only days away. Backing up to the weekend, a light onshore flow is expected to continue all weekend. Weak troughiness to our west will slowly move east causing some showers and thunderstorms, most during the heat of the day. Here in Hampton Roads, Saturday should be mostly dry although some showers could pop up in places. The coverage is expected to increase Saturday night and Sunday, but I don’t think that forecasters are expecting a widespread rain event.  This is not an easy forecast whatsoever. Winds shouldn’t be an issue this weekend (with the exception of areas affected by thunderstorms) , but forecasters will be watching that potential offshore storm come Monday for the possibility of increasing winds next week. I’ll have an update on Sunday morning.
