On the meteorological front, a shift towards wintry conditions is being forecasted by Giannis Kallianos. The forecast indicates that the upcoming days are set to witness storms, snow, and a significant drop in temperature. The pattern includes thunderstorms primarily in the southern and southeastern Aegean, northerly winds starting Friday, snowfall in the mountainous and possibly some semi-mountainous areas, and a plunge in temperature to maximums of 10-14 degrees Celsius in the lowland continental regions.
Challenges of Snowfall Forecasting
The precision of snowfall totals is difficult to predict more than a few days in advance. There's a caution against relying heavily on model snowfall graphics on social media, which often depict a single forecast from a computer model and may not accurately represent the actual snowfall. The influence of small changes in moisture on snowfall totals and the impact of a shift in the track of the surface low-pressure center on snow, ice, and rain distribution are also examined.
Long-Range Forecast Data
The latest long-range forecast data from the ECMWF indicates a strong Winter weather pattern developing for the eastern United States in January and February. The forecast data suggests the formation of a low-pressure area over the eastern United States and northern Europe, potentially bringing cold weather and snow to the region. The influential roles of high pressure over the Polar regions and the El Nino event in the Pacific on the winter weather pattern are also discussed.
Transition to a Wet and Wintry Pattern
The transition to a wet and wintry pattern in the area is evident, with moisture flow shifting from west to east of the Cascades. The return of snowfall to the mountains is expected to significantly impact travel over mountain passes. The winter weather predictions for the Ozarks highlight a slow start to winter, with colder weather expected in January and February. The influence of the El Nino event on winter season temperatures and snowfall is also discussed, providing insights into historical examples and similar winter patterns. The forecast indicates above-normal snowfall and the presence of a Modakiform of El Nino, suggesting a strong winter across much of the nation.
