Also keeping in mind that the NAM has displayed a warm bias as of late...but the cooler mid-levels and good lift make me think snow could break out until diurnal warming and WAA takes over. Yeah up in Brighton, 850mb temps will be colder so you will have more snow time! We have a chance here for an hour or two of WAA snow, but it looks more borderline across the immediate metro.. Maybe it will trend colder. |

The 18z NAM looks decent at 500mb for early Sun. A nice little neg tilt ripple to the west of us as we are in the region where cyclonic vorticity is being advected toward. The big issue is 850mb temps aren't cold enough. Still think we will see some some snowflakes Sun morning which I'll take before it changes over to all rain. It's going to be close...especially up here. This kind of caught me by surprise but I think we could see some minor accums. up this way before it turns over...but that will be dependent on the timing. It looks good in the mid-levels with good isentropic ascent and large scale lift/DPVA...and definetely cold enough at 700mb unlike the last system. NAM also brings down an area of status off the lakes which keeps overnight temps near the river valley up around freezing...hopefully that's the case. What model website do you use for isentropic features? I believe Dr. Graves has potential temperature features (290-310 K) on the CIPS model guidance. I don't look at constant potential temperature, density surface features, but I should more. For Sun morning, 850mb and 700mb winds are southerly showing clear WAA. |

The Tomer Burg site has isentropic charts or at least it did. Check back periodically to see when he gets his new site up and running. Tropical Tidbits has the 300K and 290K levels in the Upper Dynamics section. AWIPS II is by far the best tool to use for this among other things. However, it's very difficult to install, learn, and acquire data for. |

As council member in my city we are all closely watching how the larger cities manage Covid-19. This is such uncharted territory. |

Remember Mike Bush doing sports early in the morning on the radio from his home? ♫Mike Bush sports time...sports in his shorts.♫ Though I don't recommend doing that on TV |

Ya well I tried to get tested. Already used 3 days of sick time so I’m pretty much tapped out on that for now. No fever all day today so that’s a good sign I guess.

I do want to say that I love my job and am grateful to have it. The testing situation and the employers requiring a positive test to call in sick is just frustrating to see and hear.
