Lucky November 17th! Smile and say hello to some real people today. Then think about how lucky you are to be living in this era of plenty in human history!
Scroll down and enjoy the latest comprehensive weather to the max...... occurring because of the natural physical laws in our atmosphere as life on this greening planet continues to enjoy the best weather/climate in at least 1,000 years(the last time that it was this warm) with the added bonus of extra beneficial CO2.
Warm West, chilly East pattern looks to be taking shape the last week in November. Quiet.

Precipitation compared to average for the last 7, 14, 30 and 60 days.
Some spots in Iowa and especially N/C Illinois have dried out!
Usually not updated for previous day until late the next day.

Latest: The first map below is the latest. The 2nd one is from last week.
In july/August/Sept/Oct, it's typical to see some increase in drought because of evaporation, seasonally exceeding low rainfall during those months. However, this year saw a HUGE increase in the Southeast!
November 14: TOP MAP SHOWS DROUGHT DECREASED a great deal from recent robust rains. This has been the theme for several weeks now. The drought has improved immensely during that period.
The maps below are updated on Thursdays.

The top map is the Canadian ensemble average, the maps below are the individual members that make up the average at the end of week 2.
+++++++++++++++++++++++++++++++++++++++++
Each member is like the parent, Canadian model operational model.......with a slight tweek/variation in parameters. Since we know the equations to represent the physics of the atmosphere in the models are not perfect, its useful to vary some of the equations that are uncertain(can make a difference) to see if it effects the outcome and how.
The average of all these variations(ensembles) often yields a better tool for forecasting. It's always more consistent. The individual operational model, like each individual ensemble member can vary greatly from run to run.........and represent an extreme end of the spectrum at times. The ensemble average of all the members, because it averages the extremes.............from opposite ends of the spectrum.........changes much less from run to run.
End of week 2....................0z Canadian ensembles:
360h GZ 500 forecast valid on Dec 02, 2019 00 UTC
Forecasts for the control (GEM 0) and the 20 ensemble members (global model not available)
0Z GFS(American model) Ensembles at 2 weeks:
GFS Ensemble mean(average of all the individual solutions above). The first map is a mid/upper level map. The 2nd one is a temperatures map at around 1 mile above the surface. These are anomalies(difference compared to average).
NCEP Ensemble t = 360 hour forecast
Sunday: Upper level ridge in Canada and downstream trough in the East/Southeast couplet strongly favors movement of air masses from Canada south into the southeast/east half of the US. No Arctic or frigid air seen yet.
Latest, updated graph/forecast for AO and NAO here, including an explanation of how to interpret them...............mainly where they stand at the end of 2 weeks.
Previous analysis, with the latest day at the bottom for late week 2 period.

Discussions, starting with a week ago.
Monday: Not much change. Arctic cold will be aimed towards the other side of the NorthPole and Canada gets very mild the next 10+ days. AO stays negative and NAO actually drops to negative at the end of 2 weeks, so cold threats "could" return later in November.
Wednesday: The huge deal here is the NAO crashing lower during week 2. This makes the Northeast US a target for what cold there is in Canada. Also, the potential for Nor'Easters.
Thursday: Huge changes. AO increasing to close to 0 in week 2, NAO also closer to zero. This lessens the change for cold, especially frigid temps from high latitudes/Arctic.
Friday: Negative AO and NAO with positive PNA are much colder today vs yesterday. A lot of volatility and change in week 2 forecasts.......yesterday was milder, today the coldest of the week.
Sunday: Still negative AO but with huge spread from very negative up to around 0. NAO is falling in week 2 and negative but that too has a very wide spread meaning great uncertainty and potential for model to model changes. However, this strongly favors a warm West, very chilly East pattern with an upper level ridge/West and trough/East couplet that ushers Canadian air masses into the Eastern half(Midwest at times). Canada will be very mild, so the brand of cold will not be Arctic or frigid. PNA is near 0, not a factor.
