Weather Forecast Discussion The pressure gradient between a surface high pressure system centered over the Gulf of Maine and an advancing cold front from out west will allow south winds to gust quite strongly today and tomorrow (Tuesday.) This pumping in of warm southerly return flow will also allow temperatures both days to reach near record highs in the 70’s. The position of the 500mb jet moves from south of Texas to northwest of the area by early Tuesday morning. The strongest portion of the jet later weakens as it moves into the Maritimes. 850mb temperatures start around 13C today, and then 24 hours later they are a little bit higher. Then by early Wednesday morning they are about 9C and stay this way until later in the week when they begin to moderate. At 700mb there is currently a vorticity maximum out west of Texas that as time goes on through tomorrow it moves its way northeast just behind the front. By midweek it moves into the northern Great Lakes and phases with ridging over the New England states. Then models agree that a cold front will move through the area on Tuesday night, quite quickly that by 8am Wednesday morning most of the precipitation should have exited the area. Precipitable water values indicate that the area could get anywhere from 0.5” to 1.0”. Post frontal passage, flow becomes zonal for the next few days as surface high pressure builds back over the area and conditions are expected to remain dry for the rest of the work week. Temperatures for the rest of the period will be closer to normal with highs in the lower to middle 60’s with mostly sunny skies. Generally used a blend of the EURO/GFS and also the NAM for the beginning of the period. Air Quality model analysis and decision Fine Particulate: The Firework smoke model shows fire activity has significantly diminished. The last of the fires and their associated very light plumes are over mostly over the Mid-Atlantic seaboard and New England states. There will be no impact on Indiana. However, fuels are still very dry, and it will be quite windy the next few days so an enhanced risk for fire danger exists with much of the area still in a Moderate Drought. The Canadian model is going Good straight through the period. The 06Z NOAA Model is going Good today through Wednesday, for both sites. With good model consensus, and a forecast that reflects what the models are telling us, planning on going with Good through Friday. We first start off the period too windy and/or rainy for any PM2.5 growth, then after the front moves through the area, it gets cleaned out pretty good for midweek. By Friday we’re still looking at winds from the northeast which are not favorable for this development, so hence Good all around.
