On its 2-meter above ground chart, the EMCWF is showing Washington, D.C.The MOS data are showing a high of 67 and a low of 49. Clear for now, becoming cloudy tonight with a north wind becoming generally northeast at 4-5 knots. The high and low temperatures are shown to be 62.60 and 46.58. The GFS also seems to generally follow the trend of the wind directions seen on the national surface map, though the North Carolina area seems ambiguous. The MOS data are showing a high of 63 and a low of 49. Clear, becoming cloudy overnight (in the pre-dawn hours), with a northwest wind at 9 knots becoming a light northeast wind tonight. The high and low temperatures are shown to be 62.06 and 48.20. The NAM seems to generally follow the trend of the wind directions seen on the national surface analysis map provided by the NWS. Washington, District of Columbia – Today and Tonight Note that BUFKIT temperature values for the NAM and GFS have been converted to Fahrenheit from Celsius. But the NAM is showing that the inversion has lifted and the relative humidity has dropped, so the marine layer is currently negligible. According to the NAM, around 4:00 AM there may have been an inversion about 1500 feet up and as such, with over 70% relative humidity, there could have been some marine layer fog at that time. I will mention it does look like there is a trend toward there being some sort of a low over the Los Angeles area. The wind directions are rather variable around Los Angeles right now so it is hard to say what the Chinook winds might be doing. It is morning in Los Angeles right now, so we can suspect that we are entering a period of upslope winds as the mountain tops begin to heat up. Since this is less than half of five-hundred feet, and snow levels should be given increments of five-hundred or a thousand feet, I’m going to round down and stick with three-thousand feet, minus another thousand feet to give Los Angeles a snow-level or freezing-level of two thousand feet currently. Since the terrain of Los Angeles varies greatly and I don’t know exactly where the NWS is, I am going to go with the city hall elevation of about 233 feet. It is showing the wet bulb zero height a little above a kilometer, so we’ll say this about three-thousand feet above ground level. It is not the right time of year for snow – at least for the most part, as this winter and spring have been unusually cold – but for practice, I’ll go ahead and check the snow level. Be aware that this is the first time I’ve ever produced a true forecast for western and coastal weather, so some of the results of my analysis may be more of a diagnostic than a prognostic.īefore going on, I would like to dedicate this last blog post to our instructor Greg Nordstrom and thank him for all the hard work he has done to build our weather forecasting courses this past school year. for our usual model comparison and Miami, FL for coastal weather. For my locations today, I’m going out with a bang and doing three: Los Angeles, CA for western weather Washington, D.C. In the future, I intend continue using my blog for my own purposes to post my thoughts on coming severe weather events and to detail some of my storm chasing adventures. This is my last blog post for the semester – at least for academic purposes.
