They sure need the moisture due to the drought. I am waiting to see in the next 2-3 weeks if the Gulf of Alaska low temp. gives it up for a while for a -EPO to develop to start cooling us down more come mid to late Nov. I think until then, the current pattern will continue which this time of year is fine. If it lingers on towards late Nov, then our winter could be in trouble.Bgoney wrote: ↑Thu Oct 21, 2021 7:42 am The big storm in the west is still expected to stay off-shore this weekend keeping the most damaging winds away . Still expect 60-90mph gusts in the mtns. The better news is it is still going g to be an AR event and most likely record breaking for October in many areas. From NOAA:
One of the strongest October Atmospheric River events in recent memory will impact the Coastal Western United States this weekend. Recently upgraded to Category 5(!) AR status, it's not out of the question for up to 100" of snow to fall in the Sierras; 5-15" of rain elsewhere.
Awesome! Nothing like a good morning wake up call.
These storms at one time were more common in the pacific northwest. Growing up I can remember October being a very busy month for them with several big storms and a nice start to the snow pack. Alaska which got off to a great start this year in terms of snow and cold have been trending more towards the normal levels for mid-oct. Still waiting for the bigger cool down in Northern Canada and with a -NAO its not the perfect set up too get really cold. Sure they will get colder with longer nights but hopefully in early November this will change and this if this does it could mean a milder period for us between say Nov 4th-18th. Still a little to early to say this will happen but I am trying to see if the pattern switches by then.Bgoney wrote: ↑Thu Oct 21, 2021 7:42 am The big storm in the west is still expected to stay off-shore this weekend keeping the most damaging winds away .

Almost looks like that storm is trying to bow out a bit as it approaches Piqua area.
Nice post Tim , I agree with all you mention. Although not set in stone of course, that first half of November , looks like near to slightly above normal temps to average out for the period.

I think we'll see mist / drizzle / low clouds and fog with temps in the 50s.MVWxObserver wrote: ↑Thu Oct 21, 2021 7:57 am Currently tomorrow (Fri) looks dry via ILN and hopefully at least the morning hours will stay dry as my Dad has an Ace Hardware sack of nature that needs to be at the curb for pickup.
Great posts guys and I am also on board with this. For me, It's all about the 2nd half of November and if those changes that I have been mentioning occur or not. That will tell us if we are on track with our wintry ideas or if they're in trouble if the pattern does not change.Bgoney wrote: ↑Thu Oct 21, 2021 8:10 amNice post Tim , I agree with all you mention.

Hey Les I agree with your post and the further north track. I still believe though on Sunday as the warm front moves this way their is going to be a big temp contrast like I have mentioned between say Louisville and Columbus. Example would be at 1pm Sunday Louisville could be sitting at 74 while Columbus at 54 with rain. Again that warm front will head north and even folks in the I-70 area will see temps rise later in the day and several hours of dry weather before rain picks up overnight Sunday into Monday. Another thing to watch is severe weather west of here on Sunday. Tons of moist warm air moving into the system and so far its been an active severe fall season and that looks to continue. Will we getting any severe here is a much tougher question and timing is not really that good but this can lead to an uptick in rainfall especially Monday morning between say 4am-10a. Later next week will be even busier for us weather nuts.tron777 wrote: ↑Fri Oct 22, 2021 12:21 pm The only change to make to the forecast would be due to a further north track of our next system, I think showers are likely Sat night into Sun morning with the warm front. Then a break Sun afternoon (windy and warm) but I think we'll see some dry time too. Then more action Sun night and Mon with the actual cold frontal passage. I think the timing I have posted here for those with outdoor plans is looking good now. Then a break on Tues with our next system / upper low coming in later Wed thru the end of the week. Perhaps into Halloween Weekend also if the blocking is correct. Quite an active period ahead folks.
Absolutely Tim. We should start to see the temp contrast develop on Sat, later in the day then on Sunday pretty much as you have described. We're still on the same page here for sure.tpweather wrote: ↑Fri Oct 22, 2021 12:33 pmHey Les I agree with your post and the further north track.
