Medium-range guidance continues to vary on the strength and evolution of the mid-latitude cyclone forecast to be over the Upper Great Lakes/southern Ontario vicinity early D4/Thursday. Even with this variance, the overall pattern remains fairly similar with the cyclone drifting gradually eastward/southeastward into the Northeast from D4/Thursday through D6/Saturday. At the same time, upper ridging is forecast to build from the southern Plains into the Pacific Northwest/British Columbia. A belt of strong northwesterlies is anticipated between these two features, from the Canadian Prairies across the Upper Midwest and OH Valley and into the Mid-Atlantic, through the weekend. The greater low-level moisture and buoyancy will likely remain confined to the southern Plains and Southeast on D4/Thursday and D5/Friday, before some moisture advection takes it back into the central Plains on D6/Saturday and D7/Sunday. No synoptic features are forecast to interact with this moisture across the southern/central Plains, but daily afternoon thunderstorm development along the lee trough across central/southern High Plains appears possible. However, predictability of coverage and severity is low at this forecast range. Read more View the full article Quote Link to comment Share on other sites More sharing options...
