WEATHER BLOG: Last April Weekend
Some nice weather continues this weekend followed by the chance of some wet, cloudy and cooler weather moving in Sunday night and the first couple of days of the workweek, then a backing off of the rain chance as we head into Wednesday and Thursday.
High pressure ridge at the surface from eastern Quebec southward through New England and down into the mid-Atlantic with a center in north-central Pa. Saturday morning brings the sunshine with afternoon temperatures several degrees higher than Friday, putting them at or a couple of average for the date.
The overall surface ridge slides eastward Saturday and we remain dry. It looks like this surface high pressure ridge, with center roughly up in Atlantic Canada, will be nosed southwestward pretty much the rest of the week helping to influence our weather. However, we do have an upper level trough farther west out in the middle part of the country that will be tracking northeastward and weakening over the next couple of days. There is weak surface low pressure associated with this trough down in southeast Oklahoma with a warm front extending eastward. Clouds and moisture in the warm advection zone area seen coming eastward and northeastward Saturday, and our clouds will start to become more noticeable for Sunday ahead of this feature and we should end up just cloudy in the afternoon. Our temperatures will still end up comfortable despite the increase in clouds, but we may be a little too high if they thicken up quickly. The upper level trough will be open and weakening with an overall rising height field as the surface low weakens and falls apart as it runs toward the high pressure ridge. So the moisture is expected to dry out some on its eastern fringes, having a tough time progressing eastward Sunday, Sunday night and Monday.
