It’s looking to be quite an active weather week ahead as the first significant fall/winter storm of the season moves across the western states early in the week, bringing substantial snow to the mountains and even potentially some light snow to places like RNO and GEG.
Then by late week, some of the energy from that system will merge with a cold front to form another storm over the middle of the country. After a very mild early and mid week for many locations east of the Mississippi River, the late-week system will cause a cold front to sweep across and drive the temperatures way down heading into next weekend, bringing rain and some T-storms as well. There also will be several rounds of scattered showers & T-storms the first half of the week in the Midwest, Plains, and Great Lakes.
Lastly, this is where we’d like to keep saying all is quiet in the tropics. However, this week we do have some activity in the Caribbean, as Tropical Depression #18 has formed to the south of Jamaica. This is expected to become Tropical Storm Sandy very soon, and possibly approach hurricane strength in a couple of days. Current forecast tracks have it moving slowly north toward Jamaica and then up into the eastern Bahamas, before it then moves to the northeast, which would mean away from the U.S. We will be monitoring this system closely throughout the week for any potential impacts to Southwest or AirTran stations.
Here are this week’s weather highlights:
Increasing chances for showers across far south Florida as the week goes on, as the tropical system will likely bring moisture into that area (FLL, PBI, EYW). Very nice the majority of the week across the rest of Florida.
Some scattered showers around NYC up into New England Tue-Wed, but by and large nice weather much of the week from the Mid Atlantic up into the Northeast, with the next chance of showers coming next weekend (EWR, LGA, ISP, BOS, MHT, PVD, BDL, BWI, IAD, DCA, PHL, ORF, RDU, RIC).
An up-and-down week across the Midwest and Great Lakes. Very mild with scattered showers and T-storms Monday, and then a couple of dry and seasonal days. By Thursday and Friday, next system brings widespread showers and some T-storms, followed by a push of much colder air and scattered showers over the weekend, possibly mixed with some snow at a few locations (MCI, MDW, MKE, GRR, FNT, DTW, CLE, CAK, PIT, IND, STL).
A couple of chances for showers and storms across the South Plains. One on Monday, and then again ahead of a strong cold front on Friday into Saturday (HOU, AUS, SAT, DAL, TUL, OKC).
Some snow looks quite possible at DEN in the Thu-Fri timeframe, as the cold air moves down across the Rockies and meets up with moisture left over from the western storm system.
Wet and windy the first half of the week across Northern California, the Pacific Northwest, and parts of the intermountain west, with occasional showers Mon-Thu (SFO, OAK, SJC, SMF, RNO, SLC, BOI, GEG, PDX, SEA). California dries out late week, with some snow showers possible at GEG and BOI.
