Forecast 8/7/2009

Synopsis:

An upper level ridge has finally setup over the high plains. The extended ECMWF tries to keep the ridge in place over the next week but hints that it may sink south again before retreating to the north later next week.

Discussion:

The stationary front that provided the cool off the last couple of days has finally washed out and left the area under an area of high pressure. Temperatures will ramp throughout the weekend and dew points will stay up creating steamy conditions for the forecast area. Do not expect any rain chances through the weekend.

The real question is what happens next week. If the ridge is able to sink south early next week we should see seasonal conditions with highs in the mid 90's. However, if the ridge fails to retrograde, temperatures may get out of hand again. Either way, the ECMWF is trying to establish a full on omega block for late next week which will probably send temperatures above seasonal norms. Will need to monitor the upper level flow over the next couple of days to get a better handle on the extended forecast.
