For those who have donated to my site, your help has been greatly appreciated. For those not aware, donations to my site help me offset my personal out of pocket expenses…such as some of the model maps you view on here, are only available due to my subscription to the corresponding site. The F5 Data maps I post, also another out of pocket expense (monthly subscription). Updates to software (weather related), and costs for my domain name are also out of pocket to me. Any help you provide is immensely appreciated! Although it may seem I am not here and working in support of your donation, I have to work my forecasting time around my ever changing work schedule.
Good day everyone!
There is no severe weather forecast for today, however the SPC has indicated a MARGINAL risk for Severe Thunderstorms for the Central Gulf Coast in tomorrows outlook. Based on the information in the outlook, the primary threat at the moment appears to be damaging thunderstorm winds.
Elsewhere, analysis of the global models shows another large low pressure system, developing over the central U.S., and is forecast to progress toward the NNE during the next 24-48 hours, with the center remaining west of the Great Lakes region, then moving into Canada.
Models seem to be pretty much in agreement of this system not becoming to intense, with the average pressure of around 994 mb (29.35 in.). Sustained surface winds are forecast to average around 15-20 knots around the western periphery. Albeit while not very strong, it will draw extremely cold air southward, and by 72-96 hours in the forecast period, freezing to below freezing minimum temperatures will cover approximately 80-90% of the U.S. Temperatures should begin to modify over the extreme southern tier of states by Monday/Tuesday of next week.
Snowfall once again, is forecast to be limited to the Pacific NW, and eastward into the northern Rockies states. The following are the total snowfall accumulation projections from the GFS, GGEM, and NAM models for the next 72 hours:
