What’s To Blame:
A rare, deep digging trough is the culprit. So long as the jet stream smiles big over the United States, the flood gates will remain open for the East Coast. If the trough is to blame then the Bermuda High will be hit with an accessory charge. In the summer we typically focus on the Bermuda High in the Atlantic. The difference this year is the amount of moisture the dipping jet is pulling into eastern Carolina. Thus, any small lift in our atmosphere turns into a torrential downpour the likes of which are traditionally seen in the Amazon. If there is one takeaway from all of this it is that extreme weather patterns are normally assisted by features that go beyond the impacts felt at the surface. The jet stream is a big player in our current pattern and is part of the reason we’re still puddle hopping back to work this week. Adjust the jet stream and we’ll finally work out of the wet pattern (looks to be the case next weekend).
Below I’ve gathered some data to put in perspective how wet this pattern has been for us. Data locations with these records are few and far between so I only have Greenville to show:
Roasting In Death Valley:
While we are tracking record rainfall, Death Valley is tracking record heat. As of Sunday afternoon, the closest Death Valley has come to the record is 7° (127° Saturday). Keep in mind, this isn’t a traditional “hottest on this day” record. This record, if broken, will be a “Hottest recorded temperature…ever”…record. In fact, I’ve even read that an AP photographer’s camera stopped working due to the extreme heat. Sunday and Monday will be even hotter for the Valley. For what it’s worth, heath officials advise that a roast be held at 130° for 112 minutes before serving to insure safe consumption. Tough to get any closer to the definition of “roasting” than this weekend in Death Valley.
