The end of the week is almost here. Time for everyone to kick back and relax. This may be, depending on where you live, the last warm weekend of the year as October is knocking on the doorstep. We have quite a difference in areas of warm temperatures, rainy temperatures, chilly temperatures and normal temperatures all over the Nation. This forecast, which I am going to explain below, will go through Monday Spetember 26, 2011.
Everyone in the west and in the Rockies region is probably going to jump up and down seeing this graphic. Yet others will want to rip it up in pieces. Here’s the situation:
As you can see by the black/white striped going from South Dakota through Missouri up to Ohio and up in the North East fashion. This is the jet stream forecast for the next few days. Now this will fluxuate back and forth a bit but that would be the ‘centered’ point on where that Jet Stream will lay out. Now with that Jet stream forecast brings Major differences in temperatures . With that stream like that, you have a build or a rise in the Stream to the North over Montana and South Dakota. This Jet stream comes from the Pacific Ocean so this would be called the Pacific Jet in MET Terms. Now whats going to occur is that high pressure that is currently their isn’t going to move much. This is going to keep this jet stream at its current place or move slowly throughout days. With that also we have the High Pressure that is forecast to build into the Midwest locations by Friday. With that will bring Cool Air from Canada southward. That means some locations won’t get out of the 50′s in the Northern Great Lakes. Now remember that Low Pressure that I forecast to impact the North East by Thursday days ago… Well it had slowed a bit and timing was just a bit off. So it now looks as North Eastern States will see the rainy conditions all the way through Monday and May be won’t stop till Tuesday. Flooding is a potential but widespread 6 inches like a first Isolated event is not a huge bet. Most areas will see 2-4 inches in that green area. As for the south, pop up storms will likely be in company Friday and Saturday and limit to a very Isolated Event come Saturday Night. Normal temperatures in the 80′s are in the forecast. Quick jump back to the Midwest and Great lakes… Not only will you see rainy off and on conditions but it will be chilly too. So please, you can catch a cold from this weather as conditions are expected to go back to the 80′s by Wednesday.
Forecast by Color:
-Orange Area: Warm Temperature. Humid farther south you get but not un controllable humid. Due to the high, Severe weather and rain in general is not likely. Temperatures in the 80′s in the north and middle areas and 90′s are a potential down south.
-Blue: A chilly, overcast and miserable weekend as that low pressure spins and you get the backside shower activity. Won’t be a wash out but it definitively will be cool with temps in the 50′s and 60′s.
-White: Normal Temperatures for this time of year. Not crazily hot with temperatures in the 80′s. Shower or a storm is a potential on Friday and Saturday but could also occur on Monday.
-Green: Like the Great Lakes Region, A miserable weekend. Some rains that fall could “train” and cause flooding so stay tuned and turn around don’t drown. Temperatures also chilly in the mid to upper 60′s. Most areas will see 1-4 inch rains depending on location.
Hope Everyone has a great weekend! Enjoy the warm weather while it lasts! (Excuse my mistake in the word “Overcast” in the graphic. Stay tuned to Storm Central for the latest on Ophelia. We will have the latest breaking news if anything changes.
