Summer Goes On Vacation
The guidance I have examined this Tuesday morning continues to indicate we'll have an extended period of below average temperatures and it should all start next week.
Starting Wednesday, temperatures will begin to creep up and so will the moisture levels. At this time, I still don't think it will be extreme heat, but it will become quite uncomfortable and heat advisories may be needed for some.
The jet stream will buckle and that's unusual for this time of year. The western United States will bake under a hot ridge of high pressure while most of the country east of the Rocky Mountains get an extended vacation from summer heat and humidity.
The transition period starts this weekend and rain chances will begin across northern Arkansas with the remainder of the state seeing widespread showers and storms Sunday and maybe even into Monday too. While I don't expect a wash-out, there will be some much needed rain. Whenever you get into one of these transitional periods, you must pay attention to the possibility for strong to severe thunderstorms. At this time it looks limited, but it's a possibility which needs to be monitored.
