First-day play at all three boys tournaments in Bloomington and Normal was wiped out by freezing precipitation
POZ This gives the probability of freezing precipitation
during the 12 hours ending at this time.
, such as freezing rain, freezing drizzle and supercooled large droplets, fall outside the capabilities of most small FIKI-equipped aircraft.
Observations at Athens (KAHN) at the onset of precipitation [light rain (-RA); 1651 UTC 16 Feb 2015] and shortly after the onset of freezing precipitation
[light freezing rain (-FZRA); 2213 UTC], with the wet-bulb temperature estimated by the Stull [(1)], arithmetic-mean rule [(2)], and one-third rule [(3)] approximations, and as reported by the National Weather Service.
En route flight conditions (visibility, freezing precipitation
, convective activity);
Pu, "Characteristics of the raindrop size distribution for freezing precipitation
observed in southern China," Journal of Geophysical Research Atmospheres, vol.
"We expect that the number of cancellations will continue to rise as freezing precipitation
hits major airports in Philadelphia, DC and New York," the service said.
 pointed out that approximately 75% of freezing precipitation
events are a result of the second mechanism.
However, if any form of freezing precipitation
is present, the aircraft will require a higher level of protection so the two-step procedure is applied.
The nets cannot be installed and taken down daily, and if left up they could be ruined by freezing precipitation
. Additionally, the tubes used to hold the nets in place could fill with water then freeze, which could damage them, he said.
The storms had quite different histories: some produced strong winds; some produced snow, while others produced rain and freezing precipitation
; and three led to record-breaking temperatures.
This group of NWS meteorologists--called a center weather service unit--provides air traffic managers with forecasts and briefings on regional conditions including turbulence, icing, and freezing precipitation
. GAO agreed to (1) determine the status of NWS's plans for restructuring the offices that provide aviation weather services at FAA's en route centers, (2) identify FAA's requirements and its alternative sources for these services, and (3) evaluate both agencies' current abilities to ensure the consistency and quality of these services.
