Brief Cold Snap Interrupts Warmer Weather Pattern
A brief cold snap is set to disrupt a warmer weather pattern across the United States. An evolving trough system has drawn cooler air from the North Pacific, but it does not feature the extreme temperatures associated with Arctic air masses from Canada or the North Pole.
Weather Developments and Temperature Changes
This system is characterized by light precipitation and breezy conditions, although these winds are not expected to pose hazards. The current trough is the fourth in a series of systems, with the previous ones contributing minimal changes to the weather.
Impact of the Canadian Trough
Forecasts point to a smaller trough over the northern Canadian islands near Greenland. This trough is anticipated to move southward into Canada, replacing the milder Pacific air with much colder Arctic air. By early Tuesday, temperatures in this area are expected to drop below zero Fahrenheit.
As this colder air moves south, it will enhance the effects of the last clipper in the series as it traverses the Great Lakes on November 8 and 9. This system will have the capacity to draw colder air further into the United States, potentially leading to significant lake-effect snow around the Great Lakes.
Temperature Projections
- Temperatures across the eastern U.S. are expected to drop into the 20s and 30s Fahrenheit, except in the Gulf region where temperatures may stay in the 40s.
- This cold snap will be most pronounced on November 10.
Though this burst of cold is significant, it will be temporary. By November 11, temperatures in the Central Plains are projected to begin rising, with similar patterns expected across the broader central U.S. by the evening of November 12.
Long-Term Outlook
Following this cold spell, a western ridge is predicted to regain dominance later in the week. This time, it is expected to move eastward, creating a more dynamic weather pattern. This could pave the way for larger storm systems affecting the central United States.
In summary, while a series of clipper systems will bring sporadic winter-like conditions and cold temperatures this week, a shift towards milder weather is anticipated shortly thereafter. Stay tuned for updates as weather conditions evolve.
