250/500 hPa Analysis (12 UTC) 250 hPa analysis shows jet stream features (or lack thereof) Be sure to send the map to the back of the hierarchy so the Canada outline shows, then adjust the map position to fit the outline. Point out major troughs and ridges and areas without significant features. The latter are often prone to fire if unchanged over a period of a few days or more. 14H x 19W

Surface Analysis (12 UTC)
250 hPa analysis shows jet stream features (or lack thereof) Be sure to send the map to the back of the hierarchy so the Canada outline shows, then adjust the map position to fit the outline. Point out major troughs and ridges and areas without significant features. The latter are often prone to fire if unchanged over a period of a few days or more. 14H x 19W

Lightning (Thurs pm) Add lightning forecasts
Maps generated by Environment Canada – Meteorological Service of Canada Add lightning forecasts Frequency: flashes/3 hr Lightning area time coverage index Short-term lightning forecast maps from Bill Burrows at EC-MSC’s Alberta/Arctic weather centre in Edmonton These are uploaded to ftp://ftp.nofc.cfs.nrcan.gc.ca/uploads daily at about 11:00 am MDT, so we miss the morning update when doing the CIFFC briefing Normally use the 42 or 45 hour forecast, valid late afternoon the next day (which is today when doing the CIFFC briefing as explained above) LCHA (lightning area time coverage index per 3-hour period) populates a cell if neighboring cells in a 3x3 grid are expected to have lightning – probability from .005 to 1.00 LFLS (lightning flash frequency per 3-hour period) Orange indicates very frequent flashes; blue infrequent flashes 7.5H x 12.5W

NAM/GFS 500 hPa 06Z Surface NWP maps from NCEP’s NAM model run Highlight ridges and troughs and areas without significant upper air features. The latter are often prone to fire if unchanged over a period of a few days or more. Indicate areas where lightning/heat/dryness/wind may cause problems, and where significant rain is expected. t=66h Z Fri May 26 pm each 9H x 12W
14
NAM/GFS Surface NWP maps from NCEP’s NAM model run Highlight ridges and troughs and areas without significant upper air features. The latter are often prone to fire if unchanged over a period of a few days or more. Indicate areas where lightning/heat/dryness/wind may cause problems, and where significant rain is expected. t=114h Z Sun May 28 pm each 9H x 12W
15
NAM/GFS Surface NWP maps from NCEP’s NAM model run Highlight ridges and troughs and areas without significant upper air features. The latter are often prone to fire if unchanged over a period of a few days or more. Indicate areas where lightning/heat/dryness/wind may cause problems, and where significant rain is expected. t=162h Z Tue May 30 pm each 9H x 12W
16
Probability of 10 mm precipitation in next 7 days
Circles indicate forecast and/or historical locations of pressure centers. Precipitation threshold may be lower (e.g. 5mm) in dry periods.

Ensemble 7d (t=168h Tues pm)
570 dam Spaghetti plot of the 558 or 570 decameter (dam) contour from EC-MSC’s ensemble products. Forecast for 156 or 168 hours (next Tuesday morning or afternoon) Tangled lines indicate uncertainty between ensemble elements, and uncertainty in forecast conditions Tightly-bound lines indicate a high degree of certainty of contour line placement and forecast conditions 14H x 19.3W

CIFFC SitRep http://www.ciffc.ca/firewire/current.php
Summary of the next week’s national fire weather expectations: West BC/YT/NT/AB Drying and warming trend as weekend approaches Central SK/MB/NU/ON Central SK/MB/ rain South SK/MB/Northern ON getting some SH/TRW but likely not continuous East QC/Atl Places to watch: Spotty fire activity continues especially along 60N; south MB -- west ON View the latest CIFFC sitrep – this will likely be yesterday’s Summarize the expected fire weather conditions in the regions of the country indicated. Use red font for regions of intense activity Use orange font for regions of moderate activity Use green font for regions of low activity mH x nW
