DISCUSSION

Synopsis at 1830Z:

Upper ridging will gradually progress eastward through the week helping to maintain mainly dry and seasonable weather conditions. An upper trough will push through the region on Friday with a cold front Friday night and Saturday. For now, ensembles keep much of the precipitation chances off to the south and west of the CWA.

Upper ridging looks to rebound over the weekend. Look for largely dry weather and warming temperatures under the larger scale subsidence as high temperatures by Sunday reach into the 50s and 60s.

FORECAST CONFIDENCE & DEVIATIONS:

No major deviations to NBM were used for this forecast cycle. There is moderate confidence on patchy fog for Thursday morning. Otherwise there is strong consensus in support of mostly dry and seasonable weather through the week.
