Current Day 4-8 Outlook |
High Temperatures today and Friday. Widespread warmth.
Highs days 3-7. Widespread warmth to start, then chilly air invades the north while it stays very warm south.
New cold surge Northwest, then Northern Plains/Upper Midwest, then Northeast.
How do these days 3-7 temperatures compare to average at this time of year? We are now 8 weeks past the climatological time of year when temperatures are the hottest.
Well above average.............but average in mid September is not that hot anymore. With low storage, it's still possible to give a bullish kick to natural gas if it was going to last in the south.
Very cool Northwest to N.Plains, which moves east might be a bit bullish too.
High temperature departures:
Low Temperature Departures:
Dew points. 70+ on this scale makes it feel uncomfortable(sticky air)!
Humid air has been showed to the Gulf Coast and Southeast and also along the East Coast..........but is starting to return in the Plains.
Heat and high humidity COMBINED. Feels like temperature.
High Pressure in the Midwest. Warm and dry winds on the backside in the Plains. Florence getting close to the coast.
Here is the latest radar image. Florence will be stealing the show for days. Radars lighting up eastern North Carolina with spiral rain bands on the periphery, outside of the eye wall.

Satellite picture.
Very well defined Florence in the Atlantic is showing up and taking aim on the East Coast!!!
Rains the past 24 hours. Not much.

Go to precipitation, then scroll down to pick a time frame. Hit states to get the borders to see locations better. Under products, you can hit "observed" or "Percent of normal"
Too wet in a huge area from massive September rains!
Drier this week, which will minimize the problems to the crops but wet again next week from C.Plains to Western Cornbelt. Flooding from Florence coming.
Below are rains compared to average of the last 7, 14, 30 and 60 days. Usually not updated for previous day until late the next day.
Bountiful rains for most of the Cornbelt..............and points eastward and westward. This increased yields in August!!!
But September brought too much rain! Drying out now.

Drought Monitor. This product is updated every Thursday. Drought has been shrinking but still persists in Texas.........this measure takes into account the long term precip/sub soil moisture and goes back over MANY months.
Top map is this week. Map below it was last week.

Temperature Anomalies from GFS ensembles(fairly reliable product) going out 2 weeks. These maps show the Northern Hemisphere. The map of the US is front center. Look for the state borders in white.
Today/tomorrow: New cool surge Northwest. Warm Plains to NorthEast.
In 5+ days:
Very warm East. Cold in Canada hitting N.Plains on the way to Upper Midwest to Northeast.
In 10+ days:
Positive Anomalies rebuilding Plains to Midwest. Cold leaves Canada.
Day 15 Weak anomalies but looking cool.
The top map is the ensemble average, the maps below are the individual members that make up the average
End of week 2....................0Zz ensembles from Thursday..........will the jet stream buckle? Often not as good for discerning late September weather with much skill as during the Summer.
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
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.
360h GZ 500 forecast valid on Sep 28, 2018 00 UTC
The low skill, longer range CFS model for weeks 3 and 4.
Upper level ridging in Canada.
Septembers gradually gets cooler, almost every year. Heating degree days(from cold weather) will soon be replacing cooling degree days(from hot weather) as being the most important as we get into October.
Check in tomorrow to read something different............."low skill" (-:
Precip below:
Extreme weather days 3-7. Hurricane Florence and the remnants will be the highlight. New heavy rain events Upper Midwest.
