Harvey is finally accelerating away from the Louisiana region this morning and will rapidly move ENE later Thursday night. The impact on our weather will remain minimal with a slight increase in wind speeds Thursday along with a few clouds across far eastern OK.
Later Thursday afternoon as the circulation moves more to the east, the clouds will erode as subsidence slides across the region. Locations near and west of the metro will see blue sky and warm weather with highs near 87. A small window for a shower or two may persist across far southeastern OK for a few hours through midday Thursday but the odds will remain low.
Our weather looks very nice and we will continue with a dry forecast for the metro for the next few days. But this may be changing for a small window of time Saturday morning as a weak upper-level wave will drop from southwestern Kansas into north-central OK.
Some model data has been somewhat consistent with this feature and continues to develop some light precipitation with the wave Saturday morning near the I-35 region. I’m not exactly sure we’ll see too much from this feature, if anything at all, but I may need to add a slight mention since. This will be a last second, game-time decision. If I do add the pops, it will be 20 percent or less.
A major trough across the Midwest into the Yukon region will develop soon with a stout cold front moving southward early next week. The timing of the front may change a little but should be arriving sometime Monday with a slight chance of some light precipitation both pre-and post-frontal.
The early arriving in some data suggest our temps will top out in the 70s Monday across northern OK with some 80s to the south. It does appear we’re in store for some nice pre-fall conditions next week with morning lows in the 50s and highs in the 70s from Wednesday through the end of next week.
There may be another weak system developing in the southern Gulf of Mexico early next week but our above-mentioned front may help to keep this system slightly off-shore. Our friends and neighbors across southeastern TX need a break. Hopefully, they’ll get it, but it’s something we’ll be watching.
There is also a developing tropical system in the Atlantic that will become a hurricane soon. Irma will be moving eastward over the next 5 to 7 days and probably becomes a major hurricane. There is considerable spread in the data regarding the track of the system after the next 7 days. Stay tuned.
