SHORT TERM. (Today through Sunday) Issued at 220 AM CST Thu Dec 5 2019
An overall rather quiet stretch of early December weather heading into the weekend, but in typical fashion for the time of year, some pesky forecast concerns are lurking out there, mainly in the form of cloud cover at times. Early morning analysis places elongated low level ridging stretched from western Ontario down through the southeast CONUS, while a weak surface cyclone is analyzed across western North Dakota as of 06Z, tied to a fast-moving shortwave zipping across southern Manitoba. Beneath the low level ridge axis, have seen the occasional hint of some fog given light flow below 900mb and some response from recent melting snow, though think any fog formation over this way will be transient through mid morning given continued faster flow just above the surface, even as the ridge axis passes.
Both of those features will quickly advances through the area into early evening, with a cold front tied to the weak surface low clearing the area by 00Z. As alluded to yesterday, not much in the way of significant background forcing as that front arrives with the added caveat of a drier low level airmass supportive of the going dry forecast, save for perhaps far northern areas into north-central Wisconsin where just enough deeper moisture may exist for a little light snow or some freezing drizzle (lack of cloud ice) into late afternoon/early evening. Otherwise, onset of cold advection into the evening beneath residual warmth aloft is a classic recipe for lower cloud formation for at least a chunk of the night, likely clearing quickly into Friday as dry Canadian high pressure rolls through the region. Friday looking cooler as well, with highs mainly in the 20s with a shallow chilly airmass in place.
Much of the weekend continues to look pretty decent as we introduce a zonal flow regime to much of the CONUS, with strengthening southerly flow in the wake of departing high pressure Saturday supplying another stretch of mild early winter weather. Saturday looks to be the sunniest of the days, while we'll have to watch for some increasing stratus potential by Sunday as moisture begins to increase ahead of our next upper trough. Can't rule out a few showers in that regime as well given strength of the warm advection, though confidence still rather low a few days out. Bigger story is temperatures, with some spots easily pushing 40-45 today and again Saturday and probably Sunday. If (big "if") we can manage some sunshine Sunday, a few spots without snow cover could push 50.
LONG TERM. (Sunday Night through Wednesday) Issued at 220 AM CST Thu Dec 5 2019
Big changes afoot through the first half of the work week as the upper pattern transitions from a zonal regime to a highly meridional amplified upper trough as the next shot of Arctic air quickly advances into the area. Still some question about how exactly that amplification will take shape, primarily how the interaction of northern and southern stream pieces of energy will occur, but regardless of the outcome, an increasing risk for mainly light snow remains on track into Monday as frontogenetical forcing quickly increases ahead of the strong cold plunge. Otherwise, the big story will be a return to well below normal temperatures for a few days into midweek, with highs Tuesday-Wednesday likely holding only in the single digits for some areas, while overnight lows dip below zero, particularly by Wednesday morning as strong Canadian high pressure builds over the area. The moral of this story? Enjoy the 30s and 40s in place the next few days while we have them.
AVIATION. (For the 18Z TAFS through 18Z Friday afternoon) Issued at 1150 AM CST Thu Dec 5 2019
Mid to high VFR clouds will remain over the area this afternoon into this evening. Southerly winds will turn westerly late this afternoon, then northwesterly by this evening as a cold front moves through the area. Wind speeds will remain generally below 10 kts ahead of the front and increase to between 10-15 kts once the front moves through. Some lower clouds further upstream behind the surface low could bring a period of MVFR ceilings across the area overnight. Some forecast models depict these scattering out upon arrival to the area, but kept them for both sites as low-level moisture still suggests a period of MVFR ceilings. Clouds should be quick to clear on Friday as surface high pressure builds.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program. |
