Premium Weekly Outlook: Omega Block To Cause Unsettled Weather
Model and ensemble guidance are showing an omega blocking developing this week over the North America. This blocking pattern causes shortwave energy to dig into trough or phase into a cut-off low on either of side of large ridge over the Central United States. This pattern can cause cooler, wetter weather to persist for several days over the western and eastern parts of the country. In this case, models are showing waves of low pressure developing along the East Coast this week. Model solutions differ depending on how they handle upstream shortwave energy coming digging into Southeast US.
