Weather Forecast Discussion 12Z surface analysis shows high pressure over the southeastern states and some weak troughiness to the northwest. This wave will move through this afternoon and cause a few flurries and isolated snow showers, mainly over the north. Under northwest flow temperatures will struggle to get out of the 20’s for highs in the upper 20’s. For the rest of today/tonight and into Tuesday high pressure from the Great Plains will build over the area. Return flow will begin to moderate temperatures through midweek. A cold front moves through the area midweek and high temperatures dive back down into the 20’s behind it. Precipitation with this feature does not look too impressive (lack of moisture) and have low confidence that the area will see a wintry mix. Southwest flow on Friday will begin moderating temperatures back to around freezing for highs and even warmer temperatures (30’s and 40’s) for the weekend. For the most part, winds will remain at or below 10 mph, however there will be periods, such as midweek, when they gust to around 20 mph. As for the 500 mb jet, it currently dives down south of the state and is very strong, but by late tonight weakens significantly. By midweek, the jet begins to strengthen again from the far northwest, then as a lobe low pressure develops north of the Great Lakes it really picks up in speed in excess of 100 kts. This will move across the area Wednesday into Thursday and then somewhat weaken as it breaks down and moves out of the area. 850 mb temperatures start out quite chilly around -12C then warm to the freezing mark around Wednesday afternoon. They briefly take a dip on Thursday and try to start to recover by Friday. At 700 mb we start off the period with a wave to our west which will move across the area today. Then on Wednesday night into Thursday a stronger wave centered over the Great Lakes moves across mainly the northern tier of the area. This could mean some precipitation across the area during this timeframe. Generally used a blend of the EURO/GFS and partly the NAM for the beginning of the period. Air Quality model analysis and decision Fine Particulate: The Firework smoke model shows nothing but a few faint plumes across a few parts of the country, particularly across the northeast and Mid-west states, including Indiana. There will be no impact on the Hoosier state. The Canadian model is generally going with Good through the period. The 06Z NOAA Model is going Good also. (This is for both sites.) There is excellent consensus between the two models, so going with Good for today and tomorrow and then Good the rest of the period. There will be at least a disturbance midweek and then gusty winds on Thursday so will carry Good through this period. It’s possible this disturbance could clear out the area for Friday so will go with Good to end the period too.
