Two more NWS Upper Air Sites have suspended upper air launches - Omaha and Rapid City.
Here are two maps that show the degradation of our upper air network because of helium or staff shortages (or in the case of Chatham, because of coastal erosion).

Two more radiosonde sites down for the foreseeable future, and in critical areas we need them at SPC 😑😔.

And there it is — 6 more sites going to once a day launches.
Currently having to devise rigorous/systematic methods of requesting observation for forecasts & model assimilation in the Day 2-3 time range. We can request launches if far enough in advance & if staffing permits.

From knowledgeable scientists we’ve talked to, RAOBs have the second largest increase in error for upper air metrics when removed, behind aircraft data.
On average, losing RAOBs will decrease mesoscale NWP forecast skill.

Really think we need more leaders of meteorology/atmospheric science departments in this country talking about the impending attempted destruction of our field between the targeting of federal and university career pathways.

I am upping totals to 5-9" for the metro and up to 11" for along Lake Huron shoreline. Along with the snow we will get some strong winds which will lead to near blizzard conditions Sunday. There will be considerable blowing and drifting as well.

Got more snow coming this weekend quite a flip from what we had experienced most of the winter.

The Philippines have now been hit by four typhoons in the span of just 10 days.
Can't say I recall ever seeing this before.
