Ian Posted April 15, 2014 Author Share Posted April 15, 2014 GFS guidance is bullish on wind around 8pm. Two hours of TS sustained winds? Seems higher than everything else. Link to comment Share on other sites More sharing options...

Untitled-2.jpg In my experience doing WxChallenge, LAMP typically overdoes sustained, though the gusts can be quite accurate. Also, it works better in open terrain. (Ie. Great plain states, not so much urban areas). Edit: LAMP for IAD and BWI seem more logical with sustained in the low 20's and gust around 30.

Looking back, GFS has 30kts+ at 0z every run the last 4.. as high as 36kt. Link to comment Share on other sites More sharing options...

Looking back, GFS has 30kts+ at 0z every run the last 4.. as high as 36kt. Probably overdone, but looks like plenty of momentum transfer either way with temps crashing upstairs. The higher sustained stuff might be elevation dependent, imo. Link to comment Share on other sites More sharing options...
das Posted April 15, 2014 Share Posted April 15, 2014 Temp down to 43.8F after a high of 68F this morning in Clarksburg. Peak gust last hour is 41mph from the WNW. Temp drop in the last hour was 18F. Link to comment Share on other sites More sharing options...

Looking back, GFS has 30kts+ at 0z every run the last 4.. as high as 36kt. That is strange. The deterministic run has winds sustained in the upper teens. 925mb winds only in the 40s, which means that there isn't a lot of room to transfer down.

It is odd too because the other local stations only peak in the low or mid 20kts range, on MAV only around 20kts. ADW is somewhat close getting past 30.

high risk Posted April 15, 2014 Share Posted April 15, 2014 Another questionable aspect of the LAMP guidance is that it is not capturing the temperature drop associated with the front. It has DCA at 50 at 23z. I suspect that LWX's forecasts are tied at least partially into the LAMP output (or maybe MOS), but this just won't capture sharp fronts. Their zone forecast for Baltimore mentions falling into the mid 50's late this afternoon, and they have Frederick falling to near 50. Both are already colder at 3PM.
