South Florida experiences “cool front” passages fairly often during the chillier months of the year. These bring wind shifts (winds northerly and northwesterly, quickly turning to northeasterly), and a modest drop in temperatures and a more significant drop in dew point temperatures. In summer months, very weak “cool fronts” occasionally
Read DetailsA few weeks ago, I posted an article about vertical atmospheric mixing. The article focused on a single day (Oct. 10, 2016) in Portland, ME. In the article, I looked at both the variability of winds during a 24-hour period (day versus night) and also examined atmospheric soundings. Today, I’d

During severe weather situations, the media (and the NWS) are quick to note the number of people (in the 10’s of millions) who are,
Read DetailsGiven her size and strength, Category 4 (EXTREMELY DANGEROUS) Hurricane Nicole is likely to bring major impacts to Bermuda today (Oct. 13, 2016).

Read DetailsNational Weather Service (NWS) offices from Florida northward to the Carolinas have been publishing numerous “local action statements” and other information about Category 4 (Major Hurricane) Matthew (Fig. 1). Included are probabilities of various weather hazards, flooding maps, storm track maps and much more. Local media outlets, reliable weather bloggers,
Read DetailsThere’s an old expression about, “proximity.” It goes, “close, but no cigars.” That was clearly contrived in another era. However, in the case of Matthew, close may be close enough. The latest National Hurricane Center’s (NHC) projected track for Matthew brings him very close to the Florida east coast near
Read DetailsComputer models keep suggesting the development of an “omega block” across western Canada by late this week. Such a block can involve a splitting of the overall upper level wind flow by a closed high to the north and a closed low to its south (Fig. 1). Alternatively, the pattern
Read DetailsTake a look at today’s early morning (Sept. 3, 2016) Hermine forecast track from the National Hurricane Center – NHC (Fig. 1) and you’ll see several things appear to be, well, just plain weird. However, there is some good rationale behind each of these. First, Hermine is expected to slow
