More Heat, Humidity, Plus the Chance for Storms (Updated)August 6th, 2014 at 9:31 am by Tiffany Savona WAVY under Weather
Midday Update: Bertha is now a post-tropical storm with maximum sustained winds of 50mph. This means Bertha has lost its tropical characteristics and has merged with a frontal system offshore. This was the same system that brought us the rain over the past few days. A few showers and storms have already developed over Virginia Beach this afternoon. Chief Meteorologist Don Slater will be tracking the storms for you on WAVY News 10 starting at 4 PM. You can always track the rain and storms on Super Doppler 10 Live.
The 90° heat is back, but not for too long. High temperatures should hit 90° for many locations this afternoon with highs the mid/upper 80s for coastal area. We haven’t see Norfolk hit 90° for about 2 weeks now. We are also tracking a cold front that will bring us a chance for showers and storms this afternoon. The cold front won’t move in until after midnight so any storms that develop this afternoon will be along a pre-frontal trough (wind shift line) and will likely be hit or miss. Storms will be possible anytime after 12 PM. Our Future Trak model has a few storms developing by 2 PM. Any storm that develops could be on the strong side with gusty winds and heavy rain as the main threats.
Rain chances will be a little be higher tonight as a cold front gets closer to the region.
Cold front will move through Hampton Roads after midnight tonight and should be south of the area by tomorrow morning. Thursday is looking cooler and drier overall with highs in the lower 80s and lower humidity.
Tropical Storm Bertha is still spinning out in the Atlantic and has maximum sustained winds of 50mph. Bertha is currently moving over an area with high wind shear. This should help weaken Bertha even more. The latest forecast from the National Hurricane Center has Bertha weakening to an area of low pressure early tomorrow morning. I wouldn’t be surprised if Bertha weakened to an area of low pressure tonight.
Bertha does not pose any threat to land, but it did impact use here in Hampton Roads yesterday. We saw higher waves yesterday and a high risk for rip currents. Wave heights will not be as high as yesterday, but will still be running above normal during the day today. Here is your beach forecast. The water will still be rough for swimmers, so swim near a lifeguard if possible.
If you plan on beating the heat by going to the pool or to the beach, make sure you keep an eye to the sky to watch for developing storms.
While Bertha weakens in the Atlantic, the Eastern Pacific is really heating up with tropical activity. Hurricane Iselle is a category 1 hurricane and moving straight toward the Big Island of Hawaii. Iselle is forecast to weaken over the next few days as it impacts Hawaii Thursday and Friday. Julio was just upgraded to a hurricane early this morning. Julio is currently trailing Iselle and could impact Hawaii by the end of the weekend. So Hawaii could get hit by 2 storms within a couple days of each other.
