PGA Championship Weather, Cooler Temps, Hot Southwest and a Tropical Update

Sunday, August 12th, 2012

Round 3 of the PGA Championship at The Ocean Course in Kiawah Island, SC was disrupted yesterday due to a nasty line of thunderstorms, which produced gusty winds and heavy rain. My good friend Brad Nelson snapped this shot of a shelf cloud as it approached The Ocean Course.

Radar From Saturday Afternoon

This was the radar from yesterday just before the line of storms rolled into the area. The good news is that the line of storms seemed to dissipate quite a bit as it neared the course, but good call to get everyone off the course!

PGA Championship Forecast

Unfortunately, the forecast calls for more isolated thunderstorm chances throughout the day, hopefully we can get the rest of round 3 and all of round 4 in without any hiccups!

Severe Threat Today

The Storm Prediction Center has issued a SLIGHT RISK of severe weather today for areas shaded in yellow below. Hail and high winds will be the primary threat along with heavy rain potential.

Radar Simulation

One model (4km WRF) suggests that storms will be ongoing in these areas around 7pm CDT.

Not As Hot Nationally

I’m noticing a slight shift in the weather pattern across the nation… It appears that we’re seeing a little more progressive pattern, which is bringing ‘cool’ fronts across the eastern half of the nation a little more frequently. One is sliding east of the East Coast today, another is moving through the middle part of the country now and another will dance across the Great Lakes by the end of the week. The result will be cooler temperatures and in some cases it will be below average for a change!

Continued Cool… For A Little While

The 6 to 10 day temperature outlook suggests a cooler pattern across the Upper Mississippi Valley and the Great Lakes Region through the end of the month. Folks living in the northern tier of the nation might be experiencing a little fall-like weather later this week/weekend!

High Temperatures Saturday

Another cool front will drop through the middle part of the country with some coolish Canadian air funneling in behind it just in time for the weekend. Daytime highs could be in the 60s and 70s across a large area surrounding the Great Lakes Region by Saturday!

Meanwhile… It’s Still Stinking Hot in the Southwest

The National Weather Service continues there heat headlines for folks in the Southwest, where actual air temperatures could rise to 115° Sunday and Monday… YIKES!

Highs on Sunday in the Southwest

High temperatures in the Southwest look pretty toasty! Air temperatures in Phoenix could reach 110° to 115° today too.

Tropical Update

The webcam at Rodney Bay in St. Lucia shows cloudy skies and scattered showers from the remnants of Tropical Depression #7. The National Hurricane Center is still keeping a close on that wave for any further development.

See the latest conditions from Rodney Bay, St. Lucia HERE:

How About Hector

Hector Forecast Track

At this point, it appears that Hector will only be issues for ships and slow moving whales as he churns farther away from Mexico.

Thanks for checking in on this Sunday, have a great rest of your weekend and a great week ahead!
