Powerful storms hit the Mid-Atlantic region and Northeast US late yesterday and last night and this has cleansed the atmosphere of the high heat and humidity of recent days. A cold front was the main culprit of the instability and this system has pushed to a position just off the east coast; however, we’re not done with it yet. The cold front stalls out today along the coastline and tropical moisture will ride northward along the boundary zone on Friday increasing our chances once again for showers and thunderstorms. Some of the rain on Friday and Friday night can be heavy at times. The threat of showers and storms will continue on Saturday, but then decrease for the Sunday, Monday and Tuesday time period. The high heat of recent days will return in full force by early next week with afternoon high temperatures on Sunday, Monday, and Tuesday likely to be well up in the 90’s.

A rather widespread severe weather event is likely across much of the interior Northeast US and Mid-Atlantic region from this afternoon through tonight and tornadoes are certainly on the table. The main area of concern for tornadic activity extends from south-central Pennsylvania to upstate New York and Vermont...areas not usually thought of when it comes to tornado threats. The atmosphere is becoming increasingly unstable this afternoon given the combination of ingredients that includes high heat and humidity, low-level wind shear, and an incoming cold frontal system. The chance of showers and thunderstorms may decrease some on Thursday, but then it should rise again on Thursday night and Friday when moisture from a newly developing tropical wave enters the picture. This system will add some “fuel to the fire” by the end of the work week adding to chance for some heavy downpours on Friday along the eastern seaboard. The high heat of recent days will back off some on Thursday, Friday, and Saturday, but then will return in full force once again for Sunday, Monday, and Tuesday.

The high temperatures this past week in Death Valley’s “Furnace Creek” location (formerly known as Greenland Ranch) have consistently been between 125 °F and 130 °F, but this is still short of the all-time record there that occurred way back in 1913. On July 10th, 1913, the weather observer at Greenland Ranch in Death Valley recorded a high temperature of 134 °F. One hundred and eleven years later, this is still the highest air temperature ever reliably recorded on Earth. In addition to this all-time and worldwide high temperature record, the year of 1913 produced numerous other extreme weather events.

The hottest stretch of weather so far this summer season is coming to the Huntsville metro region from late this week through the upcoming weekend. In fact, temperatures could soar to the middle or upper 90’s on any day from Friday through Monday. In terms of rainfall, it looks mainly rain-free through this hot period with only isolated-to-scattered thunderstorms on the table for the afternoon and evening hours this upcoming weekend.

The hottest stretch of weather so far this summer season is coming to the Denver metro region from late this week through the upcoming weekend. In fact, temperatures could soar to the upper 90’s on any day from Friday through Sunday and Monday won’t be much of a relief as temperatures then can climb to the middle 90’s. In terms of rainfall, it looks mainly rain-free through this hot period with only isolated-to-scattered thunderstorms on the table for the afternoon and evening hours.

Humidity levels remain very high this morning in the Mid-Atlantic region with dew points - a direct measure of overall humidity - well up in the 70’s along much of the I-95 corridor. The high heat remains as well with temperatures likely to soar well up into the 90’s for afternoon highs making for very uncomfortable conditions indeed. The heat will back off some on Thursday, Friday, and Saturday, but is to return in full force by early next week with temperatures likely to soar well up into the 90’s on Sunday, Monday, and Tuesday.
In terms of rainfall, there will be an enhanced chance of showers and thunderstorms during each of the next few day and any rainfall can be very heavy at times. The combination of tropical moisture and a stalled-out frontal system will keep the atmosphere quite unstable through the second half of the week and when some daytime heating is added into the mix, the result is likely to be the development of numerous showers and thunderstorms during the afternoon and evening hours.

Rainfall has been rather sporadic in much of the Mid-Atlantic region during the past couple of months with some spots getting drenched by small-scale thunderstorms and other areas staying largely rain-free. The end result of this weather pattern has been the browning of many lawns and the need for some soaking rainfall. The best chance in awhile for some heavy rainfall on a more widespread basis comes to the Mid-Atlantic region in the time period from later tomorrow into the upcoming weekend. The combination of tropical moisture associated with Beryl’s remains and a stalling frontal system along the coast will enhance this chance for heavy rainfall and, hopefully, there will be some improvement to area lawns.

It’ll be another day featuring high heat and humidity in the Mid-Atlantic region with weak high pressure in control of the weather. Temperatures later today should peak in the middle 90’s and humidity levels will be very uncomfortable with dew points in the 70’s. While there can be an afternoon or evening shower and thunderstorm, a much better chance for rain comes in the Wednesday-to-Saturday time period and some of the mid and late week rain can be heavy at times. The combination of the tropical moisture associated with Beryl’s remains and a stalling out frontal system near the coast will enhance chances here for some heavy rainfall beginning later tomorrow and likely continuing right into the upcoming weekend. The remnants of Beryl are currently centered over southwestern Arkansas and they’ll move northeast rapidly reaching the Ohio Valley by later tomorrow and this positioning will add to the instability along the eastern seaboard at mid-week.
