Greetings to everyone!
Please be aware, even though I do not post every night, rest assured I am continuously monitoring various areas for any significant weather. I will be taking Sundays off (family time), unless we have active systems that may be posing a threat (i.e. Tropical, Winter Weather, Coastal Storms, etc.).
The SPC has issued a SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS MUCH OF THE SOUTHERN PLAINS AND SURROUNDING AREAS…
Thunderstorms — including risk for large hail and locally damaging winds — are expected Tuesday across portions of the southern Plains region and into eastern Kansas/western Missouri/Arkansas.
The SPC DAY 2 Severe Outlook will be linked to the very first SPC graphic, so you may view it in its entirety.
SPC DAY 2 CONVECTIVE OUTLOOK
Based on analysis of the SPC DAY 2 outlook, forecast atmospheric conditions are a little complex. However, based on the premise of outflow from early morning convection, favorable deep layer shear, and increased destabilization from the outflow of earlier storms, greater potential for organized, rotating storms and tornadic activity will lie within the SLIGHT risk area. One item of note, yesterday evening, the SPC had only issued a SLIGHT risk in the Day 2 outlook. As this outlook became today’s outlook, SPC had upgraded to a small MODERATE risk area. Based on forecast indices this evening, don’t be surprised if the SPC upgrades to a possible ENHANCED risk tomorrow. Please refer to the SPC home page link further in this synopsis, to access the DAY 1 outlook tomorrow
Based on analysis of the current NAM – WRF model run, the following maps indicate where the highest probability lies for the strongest of the severe weather categories based on forecast severe weather indices:
F5 DATA NAM-WRF 1:00 P.M. CDT
F5 DATA NAM-WRF 4:00 P.M. CDT

TROPICAL WEATHER OUTLOOK SYNOPSIS
The following is the list of storm names for the 2021 Atlantic Hurricane Season.
Ana Bill Claudette Danny Elsa Fred Grace Henri Ida Julian Kate Larry
Mindy Nicholas Odette Peter Rose Sam Teresa Victor Wanda
As a storm becomes named, I will be marking it in bold red to keep track of the activity for this Atlantic season. Beginning this season, the WMO has decided to no longer use the Greek alphabet, and came up with an alternate list of names, should we go past the names above. The list of names are as follows:
Based on my analysis of global models this evening, and the current run of the ECMWF EPS Cyclone development probability modeling, tropical cyclone development is not expected during the next 5 – 7 days. Satellite loop imagery doesn’t really indciate any areas of interest. There is a flareup west of Africa, south of the Cape Verde islands. However this is thunderstorm activity confined to the ITCZ. Dry air still covers a good majority of the Atlantic basin.
One thing I did notice in analysis this evening, it appears the MJO (Madden Julian Oscillation) may try to move into the favorable phases for development on our side of the world. The ECMWF, ECMWF ENSEMBLE, and JMA forecast indicate this by forecast members (yellow lines) trying to make it to phases 8 and 1. You’ll also notice in the MJO filtered VP200 forecast map how the favorable area moves closer to the EPAC and GOMEX in the week 2 forecast period. I will continue to monitor this to see if there is any consistency to the forecast.
