Heat Humidity 90s Friday Severe Weather Risk Saturday Warm Less Humid Sunday Into Monday
We are here at the cusp of the July 4th holiday weekend. After days of dealing with whether a cold front was going to move and keep on moving we can finally settle on the idea that the weather front will keep on moving. It is also moving along a bit faster than advertised and that speaks to the dominant northwest flow that will carry our weather right through next week.
Let’s start with today where we are going to see hot and humid conditions. Skies are clear on the satellite loop but you can see the cold front on the upper left as clouds develop and move through the Great Lakes. The one change in today’s out look is that we have added the chance for a scattered thunderstorm that could develop. The faster moving front is creating a more unstable atmosphere in the middle of today’s daytime heating and high dew points. Highs will reach the low and even a few middle 90s.
Watch for that thunderstorm chance between 3pm and 8pm and again it is a scattered risk so not everyone sees it. Tonight will be very warm and humid with most lows in the upper 60s to middle 70s. Saturday we have the cold front to deal with and another day with a very unstable atmosphere. More clouds will probably mean for slightly lower highs. mostly mid to upper 80s.
This has created an area of severe weather risk that has been expanded by the Storm Prediction Center from Northeast Virginia to Southeast New England. Strong winds are the biggest issue here with tornado risk running under 2 percent. Mid to late afternoon seems to be the time frame for the highest risk for thunderstorms.
Since the front is coming through faster and it keeps on moving, we are in good shape for Sunday and for Monday the 4th of July. Both days will feature a good deal of sunshine. Dew points will drop into the 50s and even a few 40s Sunday afternoon inland. Highs will be in the low to mid 80s.
Monday looks good too with sunshine though the humidity will come up a bit. Dew points will rise to the upper 50s and lower 60s. Higher than Sunday yes but still not mad. Highs will be in the 80s. No rain is forecast for Sunday and Monday. Longer range sees two more cold fronts coming through in this wash rinse repeat pattern with a chance for showers and thunderstorms Tuesday and again Thursday. No heat waves in sight in this weather pattern as Canada continues to remain busy with weather systems moving southeast in the northwest flow. Enjoy your holiday weekend.
