Blog: Heat Advisory Today. Debby Drifts In The Atlantic.

HEAT ADVISORY_1533732656894.png.jpg

I mentioned last week that some of the heat out west would move east early this week. Well.. it’s here.  Yesterday we had highs in the low-mid 90s. The heat index was near 100.  Today the high temperatures are going to rise up to the mid-upper 90s. The heat index will be between 100 and 106 in Hampton Roads. A few inland locations will have a heat index up to 109. 

  As for the weather features…High pressure is sitting offshore.  We have temporarily gone into our typical Summer pattern where the Bermuda sits offshore and pumps in the heat and humidity into the eastern U.S. 

There is a cool front over the Midwest, but it is moving so slowly that it is almost stalled out. Locally, we’ll have partly cloudy skies today with only some isolated showers and storms this afternoon.  We’ll have a better chance for some scattered thunderstorms this evening.  They will migrate east after forming over central Virginia.  A few of those may have very heavy rain and some gusty winds.  They’ll decrease by midnight.  This will be a wind-shift coming through and not a front.  So tomorrow we’ll be slightly less-hot, but not enough to really notice.  Highs will be in the low 90s with some mid 90s inland.  The heat index will still be in the upper 90s to around 100, but it should stay below advisory criteria.  Skies will be partly cloudy, and we’ll have another day of isolated showers and storms during the afternoon. The front will finally slide into our region on Friday.  Surprisingly, the models don’t show a lot of rain along the front when it comes in.  Perhaps we’ll have a little drier weather in the upper levels as the winds there become more zonal (east to west). 

Unfortunately, over the weekend the front will stall out over Hampton Roads.  Now the rain chances for that time will depend on exactly where the front sets up.  So we’ll have to watch for those updates as the weekend gets closer.  At least highs will return to the 80s.

  There is a system in the Atlantic now, but it isn’t too big of a deal.  Subtropical storm Debby became tropical this morning, and the winds increased slightly. 

The system is way out to sea.  It is several hundred miles northeast of Bermuda.  It is moving to the north/northeast.  It won’t affect any land masses, and it will likely dissipate within the next 24-48 hours. 

Looking at the Pacific Ocean…Hurricane Hector still looks like it will pass well south of Hawaii.  They will have some rain bands sweeping through.  They will have some gusty winds and brief rain showers, but the worst weather will stay to their south.  I do think they will have some big waves.  It might be good for surfers.  We’ll see.

Staying with the Pacific Ocean.  I was looking at weather articles today, and I found one that talked about the warming waters near the Pacific coast.  We’ve recently heard a lot about the hot air out west and all of the problems that it has caused.  This article focuses mainly on the hot water that the pattern has created.  Coastal Water Heat Wave.
