Summer Heat Returning….
May 31, 2011

A major shift in the overall pattern will yield summer-like temperatures across eastern Oklahoma and western Arkansas this week.  The upper level wind pattern reminds me more of July or August.

 

With the jetstream north our temperatures will continue to rise.  Unfortunately the area of high pressure across the southeast will keep the humidity high.  That moist flow off the Gulf of Mexico will also promote a slight chance for showers and storms during the afternoon and evening before the sun goes down.

This week will feel more like July with temperatures 10 degrees above average.

8:45 AM Update – Isolated Showers/T’Storms
May 31, 2011

Thanks to a cold front that will eventually stall out over the next couple of hours, we have had isolated showers/t’storms around the area this morning but most of that activity continues to move off to the east…The showers/t’storms have weakened in comparison to when they were centered around N. Oklahoma / Kansas earlier this morning. Less than a tenth of an inch of rain is possible with these storms and no severe weather is expected for the rest of today.

Early June Outlook
May 30, 2011

The summer like weather will continue over the next week and most likely through at least a week or week and a half into June. The overall pattern isn’t budging which keeps cool weather in the western 1/3 of the country, warm weather in the eastern 2/3rds of the country with all of the wet weather sticking around the northern tier of the country. Long range computer models are hinting this pattern may break down somewhere around June 10th.

Warm Days & Mild Nights Ahead…
May 30, 2011

Well after severe weather last week, for THIS week expect a calmer weather pattern…With warm and humid conditions continuing and above average temperatures all the way into the weekend.

A cold front will approach our area tomorrow but should stall out just before it gets here…Depending on the exact location of where the front stalls, we will have a slight chance for thunderstorms on Tuesday. Once we get through that, models are hinting at scattered showers and thunderstorms by the weekend…But in the mean time, enjoy the warmth and sunshine with temperatures for most of us in the 90s by late week!

Spring Rainfall Will Fall Short Of Records
May 29, 2011

It is almost hard to believe. As rainy as this spring has been it has actually been worse in the past…but not by much. Since the official rainfall data has come out, the totals have been revised down slightly from the previous blog entry. Meteorological spring ends on Tuesday and assuming no more rain falls, the spring season will go down as the 2nd rainiest season on record in Fayetteville and the 6th rainiest season in Fort Smith. The only spring season that was wetter in Fayetteville was in 1898. The Fort Smith record is from 1990. The highest seasonal rainfall totals in our area were in northern Washington and Madison Counties. According to CoCoRaHs reports, Springdale had 29.71″ and Spring Valley had around 33″ for a seasonal total. For comparison sakes, an average spring produces about 13″ of rainfall. 45″ falls in an average year, in other words about 60% of our yearly rainfall has fallen in the past 3 months.

Saturday Outdoor Forecast
May 27, 2011

If you’re heading out to the lake or the park on Saturday, you’ve got some great weather ahead.  The winds will pick up between 10 and 20 mph out of the south!  Temperatures will soar into the 80’s for Saturday afternoon under a mix of clouds and sun.

Keep in mind these lake temperatures are estimates; regardless, the water will be rather cool!  Be safe everybody.

11:15 AM Update – Isolated Showers/T’Storms Possible This Afternoon…
May 27, 2011

A couple of storms off to our west have developed a little bit ahead of schedule…Isolated showers and thunderstorms are possible this afternoon but I still expect most of the activity to be this evening/overnight around the area as the warm front continues to move north. Small hail is possible within some of the stronger cells. Storm motion has been generally to the Northeast.

Slight Chance of Severe Weather Tonight
May 27, 2011

Thanks to a warm front progressing north, scattered showers and thunderstorms are possible later today…The time frame will be this evening into the overnight hours…We do have a slight chance of severe weather within some of the stronger cells but tornadic activity is not expected. If we do see severe weather, considering the amount of lift we will have in atmosphere, hail would be the main concern. Here is a look at the severe weather risk area:

Now although NW Arkansas has a slightly better chance for severe weather later tonight, a wouldn’t rule out the chance for severe weather around the River Valley.

Friday Night Storm Chances
May 26, 2011

A warm front will approach the area by Friday evening.  The front will remain across southeastern Oklahoma which means to the north of the front we’ll expect chances for showers and storms.

Storm chances will be highest across northeastern Oklahoma and northwest Arkansas.  Most likely these storms will be elevated in nature.  Hail and damaging winds are possible.  The best timing for these storms will be after 8 p.m. Friday evening through 3 a.m.
