Original Planning Outage: The Duluth, MN, WSR-88D radar (KDLH) will be down for a long-term scheduled outage for much of this week. This is phase 2 of the WSR-88D Service Life Extension Program Upgrades (SLEP). The primary goal of this transmitter refurbishment phase of the program is to perform a comprehensive upgrade of a majority of the electronic “guts” of the radar transmitter system, including replacing old fuses with modern circuit breakers, and upgrading electronic cables and connectors to modern standards from the original hardware installed in the 1990s.  Although the form, fit, and functionality of the transmitter will remain the same, the upgrade to modern hardware equipment will help keep the 24 year old radar operating smoothly for another 20 years. The KDLH radar is expected to be restored to service no later than Friday, February 1. Alternate adjacent WSR-88D radars are Grand Forks, ND (KMVX), Minneapolis, MN (KMPX), La Crosse, WI (KARX), Green Bay, WI (KGRB), and Marquette, MI (KMQT). In addition, Environment Canada meteorological radars at Dryden, Ontario (XDR) and Superior West, Ontario (XNI) that are available on the web and via some mobile phone apps provide some radar coverage over far northern Minnesota.
